Martin Diehl b5a11f9d31 fixed bug in AL, weakened correction slightly 2013-07-30 21:04:41 +00:00
Martin Diehl 81531097f1 changes on convergence tolerances of AL and Polarisation, switched back to immediate correction of stress bc but only when last two average stresses are close to each other (cosine decay) 2013-07-30 15:32:55 +00:00
Pratheek Shanthraj 03d8f14a98 introduced dynamics for high strain rate simulations. so far only works for materials with homogeneous density. the density is read in as an optional argument in the load file using the keyword 'den' or 'density'. if density > 0 then inertial terms are added to the stress equilibrium. an implicit euler time discretisation is used to calculate the inertial terms.
dynamic problems are length scale dependent so make sure the geometry size is meaningful (1 m^3 or N m^3 for example is too big for a RVE!).

not specifying a density (density = 0) will perform a quasi static simulation as before.

Martin Diehl 296a5040b9 fixed bug in initialization when reading in material.config.
Fortran does not short-circuit, e.g. (if a>0 .and. b(a) ==c) might cause an out-of-bounds error when a=-1 it'll try to access b(-1)!
2013-06-11 20:16:40 +00:00
Martin Diehl 6f7740a243 made doxygen working for MSC.Marc again, small changes on the todo-statements for doxygen, they don't work on single lines of codes but only on module/variables 2013-06-11 16:35:04 +00:00

Martin Diehl 06b977ff61 added public statements to fftw functions and constants after whole math module is private now 2013-06-06 09:25:27 +00:00
Christoph Kords 622e2dcf15 Fixed bug in math rotations: passive and active rotations were not clearly distinguished and partly mixed up; yet, luckily, only resulted in wrong output of euler angles.
Now fixed with following convention:
Rotation conversions do not switch implicitly from active to passive or vice versa EXCEPT when converting to or from any "Euler" type (Euler angles or Euler axis/angles). Those functions expect a passive rotation as input if converting to Euler type and return a passive rotation if converting from Euler type.
2013-06-05 19:10:37 +00:00
Philip Eisenlohr 84c43741a6 reworked distribution of microstructure constituents. now each material point represents "as good as possible" the fractional content of constituents.

"marc_extractData" is a simple variant of the "postResult" script that extracts all data from a macro *.t16 file (quadratic elements not yet supported) and writes it into an asciitable
"addDataToGeometry" searches for corresponding *.txt and *.vtk file in a given directory and adds the data from the *.txt file as SCALARS to the *.vtk file

first script needed an additional function in mesh that returns the corresponding node of a given ip in a specific element
2013-04-28 20:56:17 +00:00

Christoph Kords 2a6ac44496 Major restructuring of mesh.f90 due to introduction of "cells". A cell is the volume (area in 2D elements) that surrounds an ip. It is described by up to 8 cell nodes and is used to calculate ip volume, area, and face normals. It can also be used to generate a mesh for e.g. paraview that contains ip output as cell centered data.

Martin Diehl 7b87987751 introduced option for regridding to numerics.f90, working as follows:
first cut back is tried if material point model oder BVP solver does not converge.
If no regridding is enabled after max cut back, in case of non-converged material point the simulation stops and in case of non-converged BVP solver it continues.
set regridMode to 2 to enable regridding if BVP solver OR materialPoint model do not converge,
set regridMode to 1 to enable regridding if materialPoint model do not converge, non-converged BVP solver will be ignored as in the standard case.
For regridding, the load case need to have a restart freq set.

Christoph Kords bb033c5fe7 Simplified algorithm of crystallite_integrateStress while preserving (almost) same functionality.
Removed "leapfrogging" (increase of step for next guess, when last guess was ok); Replaced Armijo rule testing for step size by simple check if the residuum got better, since the former virtually did not have any effect; consistently using the 2-norm of the residuum rather than infinity-norm for the convergence check throughout the function
2012-11-06 12:35:45 +00:00

Philip Eisenlohr 5ad0eda1b6 switched saturation behavior!!
was \dot s_alpha = (1-s_alpha/s_inf)^a h_alphabeta \dot gamma_beta
now \dot s_alpha = h_alphabeta  (1-s_beta/s_inf)^a \dot gamma_beta

current form is consistent with the genmat implementation (and appears to make more physical sense). Kalidindi_etal1992 suggested this form, but altered it to the alpha-one in Bachu+Kalidindi1998... By now, it seems that some groups use alpha, others beta approach.

introduced two new absolute tolerance values for "shears" and "twinFrac" (default 1e-6).

Christoph Kords 2be331b74d In crystallite for state integrators 2 and 3: now that "stateJump" is called before integrating dotState, we have to do state = state + dotState *dt instead of state = subState0 + dotState * dt; otherwise the deltaState is lost 2012-10-22 13:34:15 +00:00
Christoph Kords 0980920b66 In crystallite: for state integrators 2 and 3 the deltaState always has to be done at the beginning of the integration, not at the end; otherwise the stiffness calculation can be completely wrong, when the state is changed after the stress integration for the central solution.
Also changed some debugging levels in crystallite and mainly in constitutive_nonlocal
2012-10-22 07:59:35 +00:00
Christoph Kords 3ecaa9e371 modified multiplication term in order to mimic a discrete distribution of dislocation sources; namely, at high resolution, when there is (on average) less than one source per integration point, a random generator decides whether there is a source in the finite volume or not; if there is one, then the multiplication turns independent of the density and depends only on the velocity/volume times a scalar factor; recovers density*velocity/lambda for large finite volumes 2012-10-19 11:40:17 +00:00
Christoph Kords 36676029e1 for state integrator 2 (explicit euler) and 3 (adaptive 2nd order euler): don't do any state evolution during stiffness perturbation, but only stress integration, since for those cases the state is not restored after every perturbation step 2012-10-19 11:20:31 +00:00
Martin Diehl b9f97ba5da unified naming scheme, fixed a bug in the new basic scheme, and added a statistic file similar to abaqus to store the information on needed cut backs and iterations for each inc 2012-10-19 08:44:21 +00:00

Christoph Kords b99a846503 new scaling feature in numerics (unitlength) did not scale the reference coordinates in the first place; now this is taken care of in mesh.f90, so scaling should work properly 2012-09-25 16:21:58 +00:00
Christoph Kords d0fd3c03c5 forgot to check in; belongs to rev 1762 2012-09-24 16:22:25 +00:00

dislocation density below a single dislocation per IP considered not significant
2012-09-04 16:56:37 +00:00
Martin Diehl 22812c9a91 some minor improvement on precision detection: checking only once (in prec and no longer in math and crystallite), added one more 4/8 switch for LAPACK, as there is no single precision FFTW, stopping compilation for spectral method if FLOAT=4
new function in IO to print integers without leading zeros, implemented it at some places in the new spectral solver (reporting still needs some serious polishing)
updated preprocessing for documentation to handle precision correctly
2012-08-30 20:26:28 +00:00
Martin Diehl 299d9e6bc4 fixed bug in seed initialization that didn't allow to redo calculations that started with a random seed. Now the whole random seed array is set to one value, previously only the first one was reported and the remaining ones were random
removed old random function used by halton
2012-08-30 14:58:30 +00:00

Martin Diehl 0959ff3299 substituted hand written matrix inversion by LAPACK version with precision selection.
also introduced check for inversion into DAMASK_spectral_Utilities.f90 for the stress BC calculation. This part is further improved by using 5% of the reference stiffness to avoid trouble in the fully plastic regime (where the stiffness is underestimated)

Test for Marc 2010 is updated because the new inversion give slightly different results near 0 (order of e-13)
2012-08-28 16:59:45 +00:00
Martin Diehl 73349d02f5 merged precision info into the file prec.f90 and removed prec_single.f90
precision information is now parsed as a makro, defined by the compiler, eg. -DFLOAT=8 for 8 byte long floats or -- in case no values is given -- for the FEM wrapper by the interface files.

Please don't forget to run setup_code.py  !!!!!!!!!!!

abaqus_v6.env is adjusted to specify the standard precision (float=8, int=4) and got some extra compilation options, some deprecated warning supressors are removed

Optional Marc modification will follow that allow automatic selection of suitable precision

Christoph Kords 4f67d04c69 new parameter "significantRho" for nonlocal constitutive law ; density below this value will hardly contribute to dislocation glide or any dislocation reaction ; old parameter "absoluteToleranceRho" is now used only for its initial purpose, namely the absolute tolerance in the state integration 2012-08-23 05:48:21 +00:00
Christoph Kords 222aed9f60 derivative of velocity with respect to resolved stress was flawed; now much better convergence of stress integration for nonlocal constitutive law 2012-08-21 14:40:01 +00:00
Christoph Kords ad7381cfdd maximum relative step length in stress integration cannot decrease below 1
intermediate tensor "A" is calculated only once before the Lp loop in "integrateStress"

some bug fixes
2012-08-14 16:58:23 +00:00
Christoph Kords f5e7d576f1 introduced annihilation of screw dipoles; so far no thermal activation, but immediate annihilation; each annihilated screw dipole leaves behind an edge jog of same length as the dipole height on the collinear system 2012-08-14 12:26:20 +00:00
Christoph Kords c1c5941733 stressAndItsTangent:
when winding forward to last substep in increment, also do the calculation if this substep is below "subStepMinCryst";
output of "wind forward" and "cutback" info only for crystallites that are still "todo"

integrateStress:
maximum component in Lp determines absolute convergence criterium:
aTol = max(maxLpComp * rTol_fromConfig , aTol_fromConfig)
this ensures that small values in Lp do not spoil the convergence, similar to the effect of the relevantStrain parameter before (not needed anymore in the stress integration)
2012-08-14 12:07:59 +00:00
Christoph Kords eae9a34c6b corrected debugging output: extreme values of returned stress and jacobian belong to cpfem debugging, not homogenization 2012-08-14 11:48:43 +00:00

Martin Diehl b2fd3e1180 introduced preprocessor identifiers Marc, Abaqus, and Spectral to enable conditional compilation. This allows deleted dummy functions that are used by one solver only.
Mainly affected modules are IO and mesh. Most of the changes in mesh result from reordering the functions when grouping them depending on their solver.
Further advantage is that FE solver do not need FFTW and kdtree2 anymore. The include files for these two libraries moved to DAMASKROO/lib now as I figured out how to use a include path in the Makefile.
Put all the files I got when testing compilation with abaqus in a folder which to become the abaqus compilation test.
2012-06-15 16:10:21 +00:00
Martin Diehl eb39d332bd ULTRA OPTIMIZATION wasnt working anymore, seems to be related to Bertholds update of ws12 and ws13. had to remove -static from optimization string to be able to link again. Added some support for IKLM, but this didn't solve the problem 2012-06-13 17:19:16 +00:00

Christoph Kords fc7b4d6471 new function stateJump, which takes care of immediate changes in the state (deltaState); this introduces discontinuities in the state evolution; therefore this is always and only once done after each integration step, so no evaluation of deltaState for intermediate steps of e.g. the Runge-Kutta integrator; otherwise integration becomes a pain without significant gain in accuracy
deltaState now successfully tested for nonlocal model; was not correct for integrators 1,4,5 before

Christoph Kords 9cbbb7cab5 Dead dislocations are treated the same as mobile dislocations for the flux part though they do not contribute to slip. By that the pileup of dead dislocations is able to diminish with time (kinetics are the same as for the glide part; this is not correct but gives valuable results).

Christoph Kords 30c55c3142 added check for unknown keywords again (in agreement with Philip ;-)
indeed 'constitution' and '/nonlocal/' are the only keywords which have to be ignored, since they are parsed elsewhere
2012-02-14 09:22:37 +00:00
Philip Eisenlohr 9b73cb3c65 removed parameter check complaining about unknown keyword as default case. there are just too many keywords that do not trigger a variable assignment to cope with them (e.g. /nonlocal/, constitution, etc.)
I suggest to kill similar logic from other files if present somewhere...
2012-02-13 23:30:59 +00:00
Christoph Kords c786336af3 reordered (and partly redistributed) error message identifiers, deleted those which are not in use anymore.

Christoph Kords 5ddade27fc changed Peierls stress to more realistic values for fcc 2012-02-03 13:12:45 +00:00
Christoph Kords d62eddc0cd corrected kinetics law and changed parameters. For solid solution hardening there are 3 parameters: the activation energy, the concentration of obstacles that determines the activation length and meanfreepath, and the obstacle size that determines the activation volume. For the Peierls mechanism there is: the width of doublekinks that determines the activation volume and the Peierls stress for edge and screw.
Still testing needed to check whether the current formulation makes sense or not.
2012-02-03 12:50:54 +00:00
Christoph Kords bbf4f25898 renamed subroutine "mesh_marc_get_mpieOptions" to "mesh_get_damaskOptions" which is now also used for abaqus and spectral input files. The only available option so far is "periodic", which allows for periodic fluxes in the specified direction. Examples for usage (add the following lines to the respective input file, in case of spectral file this goes into the header):
- periodicity in x and z direction for marc:
   $damask periodic x z  
- periodicity in y direction for abaqus:
   **damask periodic y
- periodicity in x and y direction for spectral:
   periodic y x
2012-02-03 12:37:52 +00:00

Martin Diehl c5128e94eb some f2008 standard related correction i didn't check in last time 2012-02-01 20:20:05 +00:00
Martin Diehl 800e291240 made code standard conform to Fortran 2008 (ignoring warning concerning comments beyond character 132). Basically, changing "x" format specifier to "Nx" ("1x") plus removing $ format specifier
added compiler switches for gfortran and ifort to check for standard conformity
old gnu compilers <4.4 are not longer supported because they don't provide the c binding for fftw

2012-01-30 13:52:41 +00:00
Christoph Kords 4edd824d8c forgot homogenization.f90 in last commit 2012-01-26 13:51:01 +00:00
Christoph Kords 1330576a01 added new math function "math_deviatoric33" which returns the deviatoric part of a 3x3 tensor
renamed some math functions, so that we have a universal naming scheme: for matrix multiplications use an "x" (e.g. math_mul33x3); don't use the "x" to describe the shape of the tensor that the function is applied to (e.g. math_invert33 instead of math_invert3x3)
2012-01-26 13:50:00 +00:00
Christoph Kords df931890e0 corrected typos 2012-01-26 12:50:04 +00:00
Christoph Kords 6fec57bbd7 replaced variable fraction by "timefraction" 2012-01-26 12:48:59 +00:00
Christoph Kords 5a658d1b82 dislocation velocity output for each dislocation type (edge+,edge-,screw+,screw-)
for fcc constitutive_nonlocal_kinetics is called only once and the result is used for each dislocation type, for all other lattice structures we have one call for each dislocation type
2012-01-26 07:43:36 +00:00
Christoph Kords e5407894b5 Reworked kinetics. Now there is a universal law which can be used for both fcc and bcc (and probably even hcp). It mainly consists of an athermal forest cutting part , solid solution and peierls as thermally activated processes, and viscous glide. Therefore, lots of new parameters in the material.config. Not sure yet if the values make sense though.
Also renamed some of the old parameters. 

Unknown constitutive output raises error.
2012-01-25 17:04:37 +00:00

Christoph Kords 8739b9522e dislocation stress does not add to stress field anymore, but is only available as constitutive output for purposes of postprocessing. instead, we now use a backstress term (which is added to the resolved shear stress) that depends on the gradient of excess density on the same slip system. 2012-01-17 10:26:57 +00:00
Philip Eisenlohr ab7b9247c7 final merge with edits dropped intermediately from rev 1190. 2012-01-16 15:10:16 +00:00

Philip Eisenlohr a8dece8694 adopted use of general damask package ("import damask" instead of "damask_tools") 2011-12-15 08:52:41 +00:00
Christoph Kords b2547e0117 Math inversion used to return zero (math_inv3x3) or error (math_invert3x3) for negative determinant. Now checking whether the absolute(!) value of the determinant is close to zero to avoid singularities, negative determinants are very well allowed. 2011-12-14 08:55:24 +00:00
Martin Diehl 031a00237f improved makefile, no directly linking to files of acml
corrected default pathinfo

-substituted \ in format strings with $

restructured DAMASK_spectral:
-more logical output and structure of code
-better input for spectral debug parameters
2011-12-06 16:58:17 +00:00
Philip Eisenlohr efadf9f728 mainly fixed error in output of spectral results (1:N,…) instead of (N,…)
rearranged some logic here and there.

(hopefully) improved readability of debug/standard output.

restarting logic would need some discussion with Martin/Krishna still…
2011-12-04 10:01:32 +00:00

  (grain count
   sub-block[s] of crystallite and constitutive)
2011-11-23 09:09:00 +00:00
Martin Diehl 5a1e73b53d added set_timelimit functionality to fortran-wrapper of FFTW and introcudec it to DAMASK_spectral.f90 2011-11-21 18:48:38 +00:00

Martin Diehl 5ef73e164a restructured algorithm: moved into loop to reallocate fields and replan FFTW in case resolution changes during runtime ==> regridding
introduced parameters for selective debugging of spectral code and partly introduced the advanced divergence calculation again which is controlled by debug.config
added switch in numerics to control divergence behavior (uncorrected and corrected by phenomenological factor)
added precision directive to all values I found
2011-11-15 17:54:18 +00:00
Krishna Komerla 60c9293baf restarting seems to work, spectral solver writes own defgrad to disk.

2011-11-11 14:17:43 +00:00
Christoph Kords 860594d9a4 forgot to multiply shearrate with timestep in order to get accumulated shear 2011-11-09 10:26:00 +00:00
Christoph Kords 6dc8a4d530 check for LFC only if there is any slip activity at all; also increased safety factor from 1.2 to 1.5 2011-11-09 09:55:39 +00:00
Christoph Kords 7033e84fc7 new outputs "accumulatedshear", "velocity_edge", and "velocity_screw" (the latter two replace the output "dislocationvelocity") 2011-11-09 09:22:52 +00:00
Martin Diehl de96e99bca corrected determination of restartRead from commandline (now done by FEsolving instead of DAMASK_spectral_interface)
recompiled fftw libraries with --enable-shared to make them work with f2py

Christoph Kords 34adec74e8 corrected wrong indices into state array for velocity 2011-11-07 15:17:58 +00:00
Krishna Komerla 49c0b8a3fd restructured restarting capabilities 2011-11-07 11:04:57 +00:00
Christoph Kords 7dfb96a3da constitutive_nonlocal:
dislocation velocities are stored in the state, so we actually now have three "parts" of the state, the basic states that are updated by "constitutive_dotState" come first, then the dependent states that are calculated by "constitutive_microstructure" follow, and finally we have a last part reserved for other variables that just use the memory reserved by the state array and are updated somewhere else.

constitutive:

LpAndItsTangent does not need the full state, but only the local state, so changed that at least for the nonlocal constitutive law
2011-11-04 13:12:17 +00:00
Christoph Kords 9d1bc584d0 corrected stress integration scheme: now use norm(Lpresiduum) as a target function for Armijo's rule instead of whole tensor Lp; also corrected the guess for the improvement in Lp 2011-11-04 12:57:12 +00:00
Christoph Kords ca3d21a3b6 Depending on which state integrator one uses for the stiffness calculation, the initial state has to be chosen accordingly: e.g. for FPI choose last converged state, but for explicit RK choose converged state from start of increment (in case of explicit euler no state integration at all, but only stress integration). For this purpose we also need to remember "Fe" which now follows the cutbacking procedure as it is used for "Fp". 2011-11-04 12:44:50 +00:00
Martin Diehl ee7022d8cf correctet random seed generation to work with gfortran. 2011-11-04 10:29:35 +00:00
Martin Diehl c2eac36b48 started to implement restart facilities for spectral solver.
restart write is on per default
restart read is switched on by using --restart or -r INT where INT gives step at which the calculation should restart
setting INT to a value <1 will turn restart write off
2011-11-03 19:32:11 +00:00

2011-11-02 14:38:42 +00:00
Claudio Zambaldi 447e69019c Introduced environment variable DAMASK_ROOT.
It is set in the DAMASK root folder by running damask_env.sh
Much needed in the testing routines so far (try ./testing/run_tests.py)
damask_env.sh could also trigger other scripts to get to a working setup after fresh checkout. For example it could run 
./processing/setup/setup_processing.py
./code/setup/setup_code.py
if it finds that we have a fresh checkout.

2011-10-18 09:16:18 +00:00
Martin Diehl 4989535500 new version 3.3 of FFTW. Compiled with gfortran but only for multicore support (single core library is still the old version 3.2.2). Now either POSIX threads or OMP can be used by choosing the corresponding library file
Some further polishing (besides of new description for FFTW) of the makefile
2011-10-13 12:41:01 +00:00

Franz Roters 1dd2591982 corrected wrong check of twin systems 2011-09-13 08:18:43 +00:00
Christoph Kords 7be2701989 * new output variable "internalstress", which gives the internal stress tensor
* use "math_invert3x3" instead of "math_inv3x3" for inversion of Fe
* for dislocation stress calculation: first regular case, then special case of dead dislocations in central ip
* "dv_dtau" now given for each dislocation type, so is a (ns,4) array
* deleted unused variables in "_LpAndItsTangent"
* corrected contribution of deads in "_LpAndItsTangent"
* the NaN variables defined in math did not give a proper NaN value, so use 0.0/0.0 again
* neighbors with nonlocal constitution but local properties (i.e. /nonlocal/ flag not set) are also considered for incoming fluxes
2011-09-07 11:30:28 +00:00

Martin Diehl 380a536b45 homogenization_*, constitutive_*, DAMASK_spectral_interface: did some polishing regarding init output
makefile: corrected spelling mistake
2011-08-26 13:57:29 +00:00
Christoph Kords b300cc7faa ip volume is now based on the determinant of F. "mesh_ipVolume" represents the initial volume and is multiplied with det(F) wherever the current volume is needed. Since this works for all solver types, the "volume" output in crystallite is now also correct for spectral method and abaqus. 2011-08-19 11:18:56 +00:00
Martin Diehl f99bf63397 removed functions added for debugging of divergence calculation to math.f90
corrected calculation of stress BC condition. Depending on given BC, the stiffness matrix is reduced and than inversed. Then it is filled with zeros and used for the calculation of the correct change of deformation gradient. All calculation is done using dP/dF
2011-08-10 17:45:37 +00:00
Christoph Kords 1ffb59a96a Calculation of current ip volumes now working. Crystallite output also reflects current grain volume, not reference volume. However, this is only available for Marc. Abaqus and spectral method still return the reference ip volume. The ip coordinates though are correctly updated for all solver types. 2011-08-10 16:37:17 +00:00
Martin Diehl 34de2e301b DEBUGGING VERSION for calculation of Divergence (various methods implemented). DO NOT USE. Wait for next update coming in a few minutes 2011-08-10 16:02:13 +00:00

Onur Guevenc 31b60b8814 changed debug intensity so that the artificially high stress and stiffness values in collection cycles do not get printed out anymore... 2011-08-03 17:59:31 +00:00
Onur Guevenc 4f1cb3a8af exchanged forall with nested do loops... Bye, bye smatrix warning, will miss you!! 2011-08-03 17:58:16 +00:00
Onur Guevenc 907965272b added option to build DAMASK_spectral without openMP (make OPENMP=OFF)
fixed bug in bc_temperature assignment that was hitting memory.
Temperature is taken from the first loadcase and evolves from there in an adiabatic fashion for the moment. I.e. T-specifications from later loadcases are ignored...
2011-08-03 17:57:28 +00:00
Martin Diehl b5abd6f203 adding new option OPTIMIZATION with values OFF, DEFENSIVE and AGGRESSIVE to makefile. Polishing of makefile and DAMASK_spectral.f90 2011-08-03 07:54:32 +00:00
Onur Guevenc 64435b8a97 loadcase takes 'temperature' (or 'temp') as input. Previously it was hard-wired. 2011-08-02 13:58:28 +00:00
Christoph Kords 422d6d9c6c slight correction of debugging output 2011-08-02 12:36:08 +00:00
Christoph Kords ef7405fe21 Stress integration now uses Armijo rule to find an appropriate correction of Lp: decreases step in case that residuum does not improve significantly, accelerates as usual in case of good convergence. This turned out to improve convergence behavior. 2011-08-02 11:29:08 +00:00
Christoph Kords 6f859e99de * internal stress calculation now considers dead dislocations always at the interface, not at the center of the IP volume; used to merge them together with "normal" dislocations for stress calculation.
* dislocation flux is blocked if we encounter a sign change in the resolved shear stress from the central ip to the neighbor
* do not set density to zero if below certain threshold; this creates an artificial sink term
2011-08-02 11:17:45 +00:00
Christoph Kords 0373fa64e4 have to initialize constitutive_state during constitutive_init, since the first call to constitutive_microstructure (where we already need the state) is done before the cutback scheme starts. 2011-08-02 11:10:41 +00:00
Martin Diehl 75c67f53f7 introduced alternative location for material configuration.
If present, the >>>JOB.materialConfig<<< file takes precedence over the standard >>>material.config<<<
2011-08-02 10:14:16 +00:00
Martin Diehl 564eb5009f shape mismatch in crystallite, invalid names for variables(pos, size) in homogenization corrected. polishing of DAMASK_spectral_interface and makefile 2011-08-01 18:10:55 +00:00
Martin Diehl 3adb7ab382 corrected makefile, now working again without giving standard values explicitly.
did some small modification in order to make it possible to compile with gfortran. Changed NaN=0.0/0.0 to bitwise representation (3 different ways)
2011-08-01 10:11:32 +00:00
Philip Eisenlohr 06a4ac2565 fixed bug (segmentation fault) occurring for non-renumbered meshes: ipNeighborhood building did use FE IDs of twin nodes to address memory -- dangerous..! 2011-07-31 15:42:59 +00:00
Christoph Kords fb121b1435 * boundary condition masking changed
* damper initialized with one 
* inversion of Mandelized stiffness tensor does not work, have to use plain tensor
* new functions in math that allow for conversion between Mandel and Plain tensors
2011-07-29 15:57:39 +00:00
Franz Roters aa714a3d84 some textconstants were wider than specified in the format string, this might have caused Abaqus to crash due to an illegal memory reference (signal 11) 2011-07-29 14:54:26 +00:00
Martin Diehl 72d20875de added some switches and variables to the makefile to make it more flexible
DAMASK_spectral.f90 is a "debug version" with a number of different criteria to determine divergence. will be removed later on.
2011-07-25 16:30:21 +00:00
Philip Eisenlohr 2e9c605571 somehow forgot to move the numerics.config into the config subdir... 2011-07-21 08:40:45 +00:00
Franz Roters e92e5cae53 restarting now works with Abaqus (standard, cannot test explicit due to lack of license)
you have to specify the job you are restarting from in the job description (cae), if you prepare your input file by hand this is the first line after *Heading
example: if the first job was using Oldjob.inp the first entry in the job description needs to be Oldjob (without the .inp)
as for Marc restart works only from last converged increment, i.e. ther restart writing should be specified like this:
*retsart, write, frequency=1, overlay
Overlay is not essential but saves a lot of disk space and as stated before you can only restart from the last converged increment anyway
2011-07-18 09:15:20 +00:00
Philip Eisenlohr 8c65cb9ea6 small output polishing 2011-07-15 12:25:38 +00:00
Martin Diehl 09ba92c26e added and rearranged error messages, polished output and simplified calculation of f depending on fdot or L
guessing along former trajectory is now on per default, 'guessreset' and 'dropguessing' switch it off.

Martin Diehl 56340fd487 changed input of loadcase. Now fdot (time derivative) can be used instead of velocity gradient. Velocity gradient needs to have each line fully or not at all defined, as for other loadcases the stress BCs are not known in advance. Also added the possibility to keep guessing along trajectory of former loadcase.
changed back to use the compliance of initial linear material behavior.
added counter of non-converged steps
renamed compiler flags in makefile
2011-07-13 16:33:12 +00:00

Franz Roters 18a5841bc5 keyword freq for frequency of output writing was not evaluated when reading loadcase file 2011-07-07 09:18:05 +00:00
Onur Guevenc e889b69bec Ability to define loglinear time increments by using 'logincs' or 'logsteps' instead of 'incs' in loadcase file is added. 2011-07-06 13:10:18 +00:00
Philip Eisenlohr 314adae1bb spectral solver can now write result at reduced output frequencies: use 'f', 'freq', or 'frequency' keyword in loadcase definition.
example: ... time 1 incs 100 freq 10 will write output at times 0.0, 0.1, 0.2, ... , i.e., every ten increments only.
2011-06-15 17:48:14 +00:00

Christoph Kords cac45cff96 ip coordinates are now updated every cycle; this is needed for the nonlocal internal stress fields
* Marc: node displacements are added to initial node coordinates (mesh_node0) to get current node positions (mesh_node), then ip coordinates are deduced
* Abaqus: ip coordinates are directly updated, no update of node coordinates!
* Spectral: for the moment no update of either ip or node coordinates! passing only dummy values with initial ip coordinates

2011-03-29 07:55:38 +00:00
Christoph Kords 314ca3fe7f Internal stress calculation in nonlocal model: instead of integration of excess gradients (->Bayley) we now sum up contributions from adjacent superdislocations within a certain radius R. When periodicity is used, also periodic images are considered in stress evaluation. 2011-03-29 07:34:33 +00:00
Christoph Kords 3d51dd36fa * Introduced preprocessor directives in order to suppress compilation of most write statements when using openmp. This tremendously improves efficiency of parallelization.

2011-03-22 13:40:27 +00:00
Christoph Kords b8b75edd7d no changes to previous version, just wanted to add some comment to the previous commit:
subroutine "constitutive_nonlocal_dotState" only affects the current dotState, so no need to pass the whole array as argument
2011-03-21 15:23:36 +00:00
Christoph Kords 9b1e1e35ea dotState 2011-03-21 15:18:09 +00:00
Christoph Kords 462eda6736 split parallel region in integrateStateFPI into two 2011-03-21 14:30:10 +00:00
Christoph Kords 5ee73dee72 age dotState before resetting it to zero, otherwise the statedamping does not work. 2011-03-21 13:06:11 +00:00
Christoph Kords fc6f2ae68f No need to call constitutive_microstructure at the beginning of each crystallite step, since it's already been done at the end of the previous step. Just do it once after initialization to start with correct values for the dependent state variables. 2011-03-21 10:35:42 +00:00
Christoph Kords 11138e3ee2 debugging output is now controlled by the "verbosity" parameter in the debug.config ranging from 0 (=almost no output) to 8 (=very detailed output)
0 : only version infos and all from "hypela2"/"umat"
1 : basic outputs from "CPFEM.f90", basic output from initialization routines, debug_info
2 : extensive outputs from "CPFEM.f90", extensive output from initialization routines
3 : basic outputs from "homogenization.f90"
4 : extensive outputs from "homogenization.f90"
5 : basic outputs from "crystallite.f90"
6 : extensive outputs from "crystallite.f90"
7 : basic outputs from the constitutive files 
8 : extensive outputs from the constitutive files

If verbosity is equal to zero, all counters in debug are not set during calculation (e.g. debug_StressLoopDistribution or debug_cumDotStateTicks). This might speed up parallel calculation, because all these need critical statements which extremely slow down parallel computation.
2011-03-21 10:31:17 +00:00
Christoph Kords 9d7ede7e03 extreme values of stress and jacobian now recorded in CPFEM_general. variable declaration and generation of output moved to debug module. 2011-03-17 13:13:13 +00:00
Christoph Kords 235266b169 openmp parallelization working again (at least for j2 and nonlocal constitutive model).
In order to keep it like that, please follow these simple rules:

DON'T use implicit array subscripts:
example:    real, dimension(3,3) :: A,B
                  A(:,2) = B(:,1)               <--- DON'T USE
                  A(1:3,2) = B(1:3,1)       <--- BETTER USE
In many cases the use of explicit array subscripts is inevitable for parallelization. Additionally, it is an easy means to  prevent memory leaks.

Enclose all write statements with the following:
!$OMP CRITICAL (write2out)
<your write statement>
!$OMP END CRITICAL (write2out)

Whenever you change something in the code and are not sure if it affects parallelization and leads to nonconforming behavior, please ask me and/or Franz to check this.
2011-03-17 10:46:17 +00:00
Franz Roters 97a0146672 deactivated one debug statement at the end of crystallite_updateState(g,i,e) as it leads to division by zero if constitutive_state(g,i,e)%p(1:mySize) contains zero values
statement should be changed to check for zero values
2011-03-11 10:05:30 +00:00

Franz Roters 6667e94238 abaqus routines VGETOUTDIR and GETOUTDIR do not return the trailing slash, which we assume to be there, so it has to be appended 2011-03-03 10:29:59 +00:00
Martin Diehl 138e9c43eb some comments (talking to Ricardo) 2011-02-25 16:24:23 +00:00

Martin Diehl 8cae4d609a some polishing for single precision version.
Now only prec and mpie_spectral are needed in different versions
2011-02-25 12:41:46 +00:00
Christoph Kords ad4706673b * removed calculations for dipole formation/dissociation by stress change, since it is not used anyways; also removed associated constitutive outputs from material.config
* removed input variables in constitutive_collectDotState and constitutive_postResults that are not needed anymore (because of recent changes in constitutive_nonlocal)
2011-02-25 09:53:20 +00:00
Martin Diehl cd5407b08b removed all math functions only for double precision by the more flexible counterpart, e.g. "dsqrt --> sqrt", "dsin --> sin". Should not cause any harm, as long as "implicit none" is used.
Now it is possible to compile a single precision spectral solver/crystal plasticity by replacing mesh.f90 and prec.f90 with mesh_single.f90 and prec_single.f90.
For the spectral method, just call "make precision=single" instead of "make". Use "make clean" evertime you switch precision
2011-02-25 09:25:53 +00:00
Christoph Kords 2f503f5cdb added "Lp" as crystallite output 2011-02-25 08:15:26 +00:00

2011-02-24 18:39:57 +00:00
Christoph Kords e49e5e13af * in flux calculation: take care of special case for single element model
* do not overwrite "constitutive_nonlocal_rhoDotFlux" when doing a state perturbation, so we can use it for output
2011-02-24 10:01:41 +00:00
Christoph Kords 8aef9b1c13 check for twin nodes only in direction of the surface normal. this solves a problem with models of single element thickness and periodic fluxes. 2011-02-24 09:26:30 +00:00
Christoph Kords fed53a7e60 in subroutine "mesh_marc_get_mpieOptions": need at least one additional string after keywords "$mpie" and "periodic", not two as it used to be 2011-02-23 12:33:51 +00:00
Christoph Kords 430966eb20 sorry, forgot to commit the numerics.f90, too 2011-02-23 12:30:52 +00:00
Christoph Kords 96d3682d5e * new global integer variable "numerics_integrationMode" (1 indicating integration of central solution, 2 indicating integration of perturbed state)
* combined "integrator" and "integratorStiffness" in new global variable "numerics_integrator"
2011-02-23 08:29:51 +00:00
Christoph Kords d835380bc0 * "constitutive_nonlocal_flux" is set to zero in "constitutive_nonlocal_dotState", not in "constitutive_nonlocal_microstructure"
* dislocation flux and internal stress calculation now consistent with new definition of slip system lattice according to paper (polarity of screws inverted)

2011-02-21 14:37:38 +00:00
Christoph Kords b21c153761 restructured constitutive_nonlocal_compatibility and incorporated the "surfaceTransmissivity" in the compatibility calculation 2011-02-16 16:38:18 +00:00
Christoph Kords 24d33bf2ff * added a new material parameter "surfaceTransmissivity" (default value 1.0) which allows to change the transmissivity of the material surface between 0 and 1
* now complaining when encountering an unknown nonlocal parameter in material.config
* use same error ID for all material parameters out of bounds
* symmetric flux calculation in side dotState can now be omitted (because of new treatment of periodicity)
* switching back to "local flux balance" (add leaving and entering fluxes at central MP, don't touch neighbor) instead of "flux distribution" (subtract leaving fluxes from central MP and add them at neighboring MP). This has the advantage that there is almost no need for CRITICAL statements in parallelization, so hopefully this results in some speed up.
2011-02-16 16:35:38 +00:00
Christoph Kords 8f626c8989 Now able to have real periodicity for fluxes (fluxes leaving the model on one side enter on the other side).
To enable this feature one has to add the following somewhere in the marc input file:
   $mpie periodic x y z
      for having periodicity in all directions
   $mpie periodic z x
      for having periodicity in x and z direction
   etc.
Note that this only works for regular meshes!!!

Martin Diehl 3d7fad6ba9 mpie_spectral.f90: changed fourier transormation, now using the advanced interface to do the tranformation both ways with just one call. now also using the same variable for pk-stress in both domains and the change of deformation gradient in both domains.
postprocessing: renamed name of python/f2py modul from "reconstruct" to "postprocessingMath", added some numerical operations to use for postprocessing.
2011-02-09 17:47:28 +00:00
Christoph Kords 803e1a8c05 In order to help preventing further memory leaks all array sections now have an explicit instead of assumed shape, e.g. Fe(1:3,1:3) instead of Fe(:,:). 2011-02-09 13:12:46 +00:00
Christoph Kords 466ced911e * check convergence for nonlocals also in stiffness calculation mode 2011-02-09 08:39:07 +00:00
Christoph Kords 921967c2ba * found memory leak in nonlocal model! "constitutive_nonlocal_rhoDotFlux" has to have upper index bound of 10 for second dimension, not 8.
* need to recalculate dislocation velocity in postResults, otherwise we take values of last perturbed state! So the following outputs were up to now showing the perturbed state: shearrate, dislocation velocity, all density rates!
2011-02-09 08:28:47 +00:00
Christoph Kords 17a6c0e59b enhanced comment on dislocation kinetics 2011-02-08 12:48:50 +00:00

Christoph Kords faba13f7fd * now able to introduce some scatter in the initial single dislocation density (only for nonlocal model!) ; setting the parameter "rhoSglScatter" to a positive value generates a gauss distribution for the dislocation density with standard deviation equal to "rhoSglScatter"
* dislocation stress calculation is only done for nonlocal constitution ("/nonlocal/" keyword is present in material.config)

Alankar Alankar b362755457 grain orientation shuffling was skipped for /elemhomo/. no clue why, now dropped... 2011-02-03 17:25:58 +00:00
Martin Diehl fec2c14a4e removed hard-coded tolerances from mpie_spectral and put them to numerics/IO
removed storage of full cauchy stres field from mpie_spectral.f90, only average is stored now
added cauchy stress and von mises equivalent calculation to spectral post.

Philip Eisenlohr c00a42a9a4 fixed last remaining tensor outputs to their transposed versions 2011-01-27 14:29:06 +00:00
Martin Diehl aa7d5afd94 changed ifort options back to previous ones as -fast is not working 2011-01-26 13:33:44 +00:00
Christoph Kords 05d4d5fef2 * kinetics now according to Mohles; enables solid solution hardening
* changed example in material.config accordingly
2011-01-26 10:17:42 +00:00
Philip Eisenlohr 6ac06af517 sorry, forgot to alter the most important part: post_results..! eventually, the t16 has defgrads and friends in correct format: du_i/dx_j is listed as linear array (1,1),(1,2),(1,3),(2,1),... 2011-01-24 16:23:37 +00:00
Philip Eisenlohr 4ee40df5ba transposed writing into t16 file (and screen/debug) did not work with just stating array(1:3,:)...
fixed by using math_transpose3x3 (and similar) instead.
2011-01-24 15:02:19 +00:00
Philip Eisenlohr 794aeb253b crystallite and CPFEM now print/output tensors in ij notation (used to be, particularly in the t16, ji, i.e. transposed...)
math reports random seed used for rnd() generation
2011-01-20 19:25:45 +00:00
Martin Diehl b546d3bb91 some corrections regarding Multicore-support on mpie_spectral.f90 and makefile
slight changes on mpie_spectral.f90 regarding file output
2011-01-12 17:02:42 +00:00
Christoph Kords 062c6b3d54 * allow zero cutoff radius
* added missing error codes
2011-01-12 12:36:48 +00:00
Christoph Kords d92f992eb7 if nonlocal ip has local neighbor assume perfect transparency of the (perhaps virtual) phase boundary. this is only a quick fix! need to rethink the way constitutive and real boundaries are treated! 2011-01-11 18:00:29 +00:00
Christoph Kords 6a3dd78259 fluxes are disabled when keyword "/nonlocal/" is omitted in the material.config (this is a way to use the constitutive_nonlocal model as a local dislocation based model) 2011-01-11 14:55:36 +00:00
Martin Diehl ccc6aac10b did not delete mpie_spectral2.f90 properly 2011-01-07 13:11:32 +00:00
Martin Diehl 71fb5eedf2 changed makefile: material subroutines are now compiled using openmp, enabled linux threads for fftw3 (also did some slight changes to enable that in the fortran source code)
renamed mpie_spectral2.f90 to mpie_spectral2d.f90 (testing file, not properly working at the moment)
changed file extension and variable names in mpie_spectral.f90 and mpie_spectral_interface.f90 from "mesh" to "geom". Removed direct output from mpie_spectral.f90, all output is now base on materialpoint_results(:,1,:)

Franz Roters 9447330ab0 ATTENTION repository has been moved to new server!
Now at musvn1:/home/svn/repos/cpfem
2011-01-05 16:11:51 +00:00
Franz Roters 096a4803b0 some polishing concerning openMP initialization
number of threads is now written to *.out file
2010-12-02 11:04:29 +00:00
Denny Tjahjanto 36f27edd75 1. Adding more comments
2. Changing 'subroutine' into 'function' for optimizing the computation time
2010-11-26 11:50:20 +00:00
Christoph Kords 6b199e7830 allow 2digit values to be read in for MPIE_NUM_THREADS 2010-11-25 10:34:55 +00:00
Christoph Kords ea6a6c9503 * environment variable MPIE_NUM_THREADS now determines number of threads used in parallel regions
* default value of the OMP_NUM_THREADS variable has to be restored at the end of mpie subroutine, since marc also seems to use and change(!) this 
* usage: "export MPIE_NUM_THREADS=<number of threads>" to set variable in shell, then restart mentat and compile with option 3 (at the moment this does only work on ws 6, since all other workstations use compiler option "-save"; this puts all local variables by default in static memory, which is a killer for parallelization!)
2010-11-19 17:45:27 +00:00
Christoph Kords b9b226548c * enclose wall time measurement for LpAndItsTangent and count of leapfrogbreaks by CRITICAL construct
* better use SINGLE (having an implicit barrier at the end) instead of MASTER construct
* deleted all explicit BARRIERs after do loops since parallel loop construct implies barrier at the end
2010-11-19 17:29:29 +00:00
Christoph Kords 15728d3305 enclose wall time measurement for dotState and dotTemperature function by CRITICAL construct 2010-11-19 17:19:03 +00:00
Christoph Kords 4f267f4375 parallelization now works properly (not yet tested extensively though):
* had to add some BARRIER constructs
* only the master thread is allowed to increase the state counter

yet parallelization seems not to give a significant decrease in calculation time with nonlocal model (because of too many CRITICAL statements?)
2010-11-11 16:16:05 +00:00
Christoph Kords 14594dc9e2 * OpenMP does not like unbounded array subscripts in function calls
* some write statements were still not enclosed by CRITICAL construct, some needed a MASTER construct
2010-11-11 13:14:53 +00:00
Christoph Kords bca951325d * cpfem will now produce a warning if all components of the stiffness tensor are close to zero 2010-11-04 18:18:01 +00:00
Philip Eisenlohr 54748bb6a5 cycleCounter reset was 0 now -1 ==> occurence of jacobian calculation is now correct, i.e. always calc at start of new increment 2010-11-04 18:15:50 +00:00
Christoph Kords 405d5529e7 * checked and corrected parallelization of code. compiles now successfully, but simply aborts computation with first parallel directive without any comment :-(((
* also put a call to constitutive_microstructure at the start of each crystallite_integration subroutine like it was before. need that for nonlocal model in case of crystallite cutback
2010-11-03 17:22:48 +00:00
Philip Eisenlohr 0dd99cb965 lattice: (re)introduced _symmetryType function to replace unsafe lookup array
numerics: polishing

mpie_cpfem_marc: polishing

..powerlaw: aware of symmetryType function

crystallite: aware of symmetryType function, smaller leapfrog acceleration

IO: new warning 101

CPFEM: range of odd stress is now -1e15...+1e15, H_sym is used for stiffness
2010-11-03 14:58:11 +00:00
Denny Tjahjanto 763c20b302 Introducing the capability to restart jobs that crashed in the middle of sims. At the moment, this feature is exclusive for Marc.
Major changes:

CPFEM.f90 => 
1. Moving the initialization out of CPFEM_general into a separate subroutine, which is directly called by the hypela2 (Beware, the Abaqus version must also be modified in order to adapt with this change).
2. Restore primary state variables in CPFEM_init from binary files when requested (Marc flag: restart read).
3. Writing primary state variables into binary files (Marc flag: restart write).

FEsolving.f90 =>
1. Adding functions to recognize Marc restart flags: read and write and the corresponding restart file (parent job).
2. Change the initial value of cycleCounter = -1 in conjuction with the change made the ping-pong scheme

homogenization_RGC.f90 =>
1. Just syntax polishing.

IO.f90 =>
1. Adding functions/subroutines to open binary files for writing the primary state variables for restart purpose.

mpie_cpfem_marc.f90

1. Modification of the general scheme for collection and calculation in order to accommodate the newly added restart feature.

Christoph Kords 4c20daa00d state loop count was wrong for adaptive euler integration 2010-10-28 12:22:17 +00:00
Martin Diehl 17812c1f9e added raw output, gmsh output is still included 2010-10-27 17:15:49 +00:00
Christoph Kords 9320d48305 in RKCK45 state integration: dotState was not saved in last Runge-Kutta step 2010-10-27 08:48:04 +00:00
Christoph Kords f5f3ef5ecc * have to reset dotState to zero before call to collectDotState (only important for nonlocal calculation)
* in Fixed Point Iteration: update dependent states after state preguess was missing; on the other hand, the first call to constitutive_microstructure was obsolete
2010-10-26 14:04:33 +00:00
Christoph Kords 4439282239 no change to previous version, just forget to mention one important change of the last revision:
* fluxes are now again calculated and distributed only! by the originating material point. this means that the central MP might change the dotState of its neighbor. have to see whether locks slow down parallel computation
2010-10-26 13:49:58 +00:00
Christoph Kords 62d06001ea * corrected compatibility for screws (always positive)
* detection of grain boundary in constitutive_nonlocal_microstructure with the help of transmissivity
* enforce positive densities in constitutive_nonlocal_microstructure (needed because dotState does not create cutbacks for negative densities anymore)
* reset single mobile densities below certain threshold to zero (also done in constitutive_nonlocal_microstructure)
* constitutive_nonlocal_kinetics only gets local state variable as input, no need for the entire array here
* dv_dtau is always positive
* multiplication is only active when there is already some initial density of the respective type
2010-10-26 13:42:18 +00:00
Christoph Kords 366d52bd71 * former "relevantRho" and "relevantResistance" is renamed to "atol_rho" and "atol_resistance" and now used as an absolute tolerance for the state residuum. before it was used rather as significant state, so whenever the state dropped below that value it was considered converged. (In dislotwin and titanmod constitutive law there is only one value atol_rho which is used for all the states, though the state array consists not only of densities. We need further parameters here!)
* somewhat simplified convergence check for adaptive euler and runge-kutta
