Pratheek Shanthraj fd94c786f0 moved stiffness tensor calculation to lattice
introduced 'isotropic' and 'orthorhombic' lattice types to use corresponding symmetries in stiffness tensor. intended to be used with non-crystal plasticity models (j2, constitutive_none with isotropic, cubic or orthotropic elasticity).

Martin Diehl c6a79d2b3d divergence_correction for basic solver variants has now 3 possibilities:
0: uncorrected, slope per sidelength (physical dimension) e = res/dim
1: corrected by sidelength, slope per unitlength          e = res/1
2: corrected such that distance between FPs               e = 1

alway regarding the medium length of x,y,z direction

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.

enabled restarting for Basic PETSc variant

Martin Diehl c831716b26 reseting value vector when reading in for loadcase file, otherwise NaNs might be in there 2012-11-08 20:35:31 +00:00
Christoph Kords 11264f3fe4 forgot to check for convergence flag in FPI integrator 2012-11-08 20:15:19 +00:00
Christoph Kords 60438cdbcc criterion for crystallite cutback loop changed from crystallite_subStep to crystallite_todo; this avoids problems when the last substep of the crystallite increment is below subStepMinCryst (which is allowed during last wind forward)
fixed bug in the adaptive Euler integrator and the RK4 integrator, which could not reach the stateJump function, because of erroneous check for converged flag; also corrected the state counter for the RK4 integrator
2012-11-08 20:00:29 +00:00

Christoph Kords c775edaa6d better avoid initialization of residuum_old with huge, since it posed problems in Abaqus 2012-11-08 13:26:22 +00:00
Christoph Kords dad9922f54 fixed bug in crystallite_FPI: stateDamper always has to be defined for each grain
added some OMP FLUSH statements were necessary 
replaced openmp do by forall construct where possible; this is much safer and perhaps even as fast for small loops
2012-11-07 15:43:29 +00:00
Martin Diehl bbcffa668b some small changes in including PETSc *.h90 files to prevent warnings.
It seems that a bug in old gfortran 4.5.0 causes the problems, at least with 4.7.3 it seems to work after fixing the bugs in IO.f90
2012-11-07 13:11:41 +00:00
Martin Diehl 9b99825ac6 preventing array index out of bounds in case of empty line, removed to goto statements 2012-11-07 09:31:46 +00:00

still not running with gfortran, use at own risk!
2012-11-06 16:00:51 +00:00
Martin Diehl a86d528a4a replaced call flush(6) by flush(6), slightly improved formating for output of gfortran version 2012-11-06 15:50:20 +00:00
Christoph Kords 5b6baa7c0d introduced distinction between ip coordinates and cell center coordinates; the former can be globally calculated by subroutine mesh_build_ipCoordinates, the latter locally by the function mesh_cellCenterCoordinates; renamed mesh_ipCenterOfGravity to mesh_ipCordinates 2012-11-06 14:37:13 +00:00
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
Christoph Kords 639d6e0655 inserted missing flush(crystallite_todo) in parallel section; might have caused trouble in parallel calculations before 2012-11-05 14:45:52 +00:00
Martin Diehl 086fe138b1 substituted matrix inversion to solve equation by direct solution routine from LAPACK 2012-10-31 09:56:26 +00:00

Christoph Kords f666f8dcf3 added possibility to scale the plastic shearrate by the ratio of mobile to total density; keyword in material.config is "deadZone" 2012-10-29 12:49:28 +00:00
Martin Diehl ca596bc7af error messages are now printed, added svn properties 2012-10-25 09:16:17 +00:00
Christoph Kords 93cc466749 third entry in mesh_ipNeighborhood stores the neighbor_index that points from each neighbor back to the central ip; needed in nonlocal model 2012-10-24 14:03:02 +00:00
Martin Diehl 13b55275b1 documented utilities and structured, worked on the restart capabilities of the new basic solver 2012-10-24 11:31:40 +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).
2012-10-22 14:55:07 +00:00
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

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)

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

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

Martin Diehl 8537e87b7e added shell scripts to run tests from crontab, improved numbering in spectral compile tests and added some first files for testing restart capabilities of spectral solver.
added configuration file for generation of code documentation using doxygen
restart of spectral solver is fixed and seem to work now also for restart at significant deformation.

Franz Roters 380f40561b first calculation of Tstar still used hard coded Hooke, now usese constitutive_TandItsTangent(...) 2012-06-18 07:26:34 +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 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

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 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.

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
added draft for compilation test of spectral solver

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

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

Philip Eisenlohr b9647b2584 moved parts into new "lib" folder 2011-11-03 13:21:11 +00:00
Martin Diehl 680ba9082f removed deadlock when calling IO_warning(33)
polished IO_error and IO_warning
checked OpenMP critical statements in DAMASK_spectral.f90
corrected writing of headed in DAMASK_spectral.f90

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.

Martin Diehl 15c356c3a7 some small improvements regarding the rotation of the loadcase frame 2011-10-25 13:38:24 +00:00
Martin Diehl c13aa2a829 first try of implementing a rotation of the loadcase coordinate system. Seems to work so far for one loadcase and homogeneous materials. 2011-10-24 18:26:34 +00:00
Martin Diehl 0f34d14bee again edited the makefile, no there is more flexibility in defining the libraries (FFTW and ACML)
added the source of fftw-3.3.tar.gz to fulfill the GPL
set_python_env.py was forgotten during last commit (for testing)
2011-10-24 16:57:51 +00:00
Martin Diehl 8ac1891b3c moved DAMASK_NaN to prec.f90 respectively prec_single.f90 as it is precision dependent 2011-10-20 16:46:11 +00:00
