Pratheek Shanthraj 4b7890f133 fixed wrong indices in analytic jacobian calculation following christoph's changes. convergence is restored at least for the spectral solver 2014-01-22 10:16:55 +00:00
Christoph Kords 3dfdbaff5b Fixed wrong indices in tangents dT_dFe and dFe_dLp, which however luckily did not have any effect in the perturbed stiffness since they were transposed such that the double contraction of both remained unchanged.
In contrast, the analytical jacobian will probably be affected by this change!
@Pratheek: Can you check with me how this can be fixed?

Christoph Kords c10d0d15cb crystallite_integrateStateFPI: convergence check always ran about all e,i,g; now checking only those specified in FEsolving_execElem, FEsolving_execIP 2014-01-21 18:45:41 +00:00
Christoph Kords ff648492c1 perturbation calculation in crystallite_stressAndItsTangent: only backup and restore those chunks of crystallite_Fe, _Fp etc that are actually used in order to avoid pointless data copying in non ping pong mode

Philip Eisenlohr 74cbfb6d48 added few comments 2014-01-17 01:38:35 +00:00
Christoph Kords 77cba87bf3 in crystallite_integrateStress: pass full 2nd PK stress to LpAndItsTangent instead of only the deviatoric part; otherwise constitutive laws that depend on the hydrostatic pressure do not work; constitutive laws that require a deviatoric stress need to calculate it internally (as is e.g. already done in the J2 model) 2014-01-16 10:36:40 +00:00

2013-08-08 15:00:22 +00:00
Christoph Kords 3fcc00910c fixed bug that occured under marc (and abaqus?) with openmp:
"lastLovl" (for marc) and "lastStep" (for abaqus) have to be global module variables in FEsolving.f90 instead of local variables in the respective DAMASK_* files; otherwise they are initialized with zero each time hypela2/umat is called.

Christoph Kords 9f0fe873ba plain mode (no ping pong) now seems to work for marc, further testing needed
regular sequence of computation modes is

          7,1,1,…
          0,0,0,…
          1,1,1,…
and so on

after a cutback the computation modes follow as
inc 5: 8,0,0,…
          1,1,1,…
          0,0,0,…
          1,1,1,…

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.

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

Christoph Kords c7f987a3c1 "unitlength" parameter, which determines the physical size of the mesh, now available as a global mesh variable "mesh_unitlength" and written to the .mesh file during init.
Hence, it is available to the marc_deformedGeometry.py script via "mesh_init_postprocessing()" and "mesh_get_unitlength()", so no need for setting the scaling of the displacement vectors explicitly through an option; now displacements and nodal positions are always consistent

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.

Martin Diehl b1c3c57412 some more finetuning, still not running on gfortran 4.5.0 2012-11-08 21:33:58 +00:00
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
Martin Diehl ee5903c767 replaced real 'guessmode' with logical 'guess', caused trouble on gfortran 6.3 with ultra optimization 2012-11-08 19:32:00 +00:00
Martin Diehl 6a86f36407 now having libraries from Makefile before PETSc Libraries in linker order 2012-11-08 18:26:10 +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

Martin Diehl 3ada4897fb reordered PETSc initialization (now first part done in interface, setting of parameters done in numerics), removed unnecessary includes for PETSc
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 55dc286be2 corrected limit for upper stable dipole distance; fixed a bug in the postResults where division by zero might happen 2012-10-29 13:02:01 +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
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 6230dacbac only first broken ip signals "terminally ill" 2012-10-18 13:48:06 +00:00

added internal check against dilatation in Schmid matrices.
2012-10-12 17:59:50 +00:00

Philip Eisenlohr 1b2edd7e7d fixed error in _identity (wrong delta-function)
added _exp33 for matrix exponential
added trace33 for matrix trace
2012-10-12 17:54:20 +00:00
Martin Diehl 324dfda5a2 added comments (doxygen conform) to phenopowerlaw, added warning on specifying h0_sliptwin as it has no effect 2012-10-11 14:49:12 +00:00

put header of debugging output in constitutive_init at the start of the function in order to make debugging easier
2012-10-09 12:34:57 +00:00
Christoph Kords a84e0529c3 make correction of hardening coefficients thread safe 2012-10-05 16:05:51 +00:00
Christoph Kords 40a2e652e7 introduced material parameter "linetension", which indicates how strong the effect of the line tension on the hardening coefficients is 2012-10-05 14:42:41 +00:00
Christoph Kords 7cc6108a04 hardening coefficients for fcc are density dependent (line tension effect, Devincre, Kubin, Hoc; 2006; Physical analyses of crystal plasticity by DD simulations)
fixed bug with thermal annihilation producing negative density in case of very small dipole density and high climb velocity
2012-10-04 18:08:40 +00:00
Martin Diehl 80465c0b49 moved option for UTF-8 encoding to spectral interface as this is now called before prec init.
if UTF-8 encoding is needed for FEM solver (old compilers might not support it), add the same statement to the corresponding interface routine
2012-10-04 14:22:39 +00:00
Martin Diehl e2ea3cdff6 again some changes regarding creation of NaN, ieee-conforming way is not in the complilers yet. 2012-10-02 16:53:03 +00:00
Christoph Kords bce8012c89 random distribution of initial dislocation density now really independent of meshsize 2012-10-02 15:26:58 +00:00
Martin Diehl d5ce49c471 numerics got some protected statements and is now reading in the new keywords for the solver selection in small letters.
spectral solver got cut back facilities + improved output to screen
2012-10-02 15:26:56 +00:00
Christoph Kords 91b7883c2a random distribution of initial dislocation density now independent of mesh size 2012-10-02 13:35:34 +00:00
Christoph Kords 1502a71f0c added possibility to start with an initial random distribution of dislocation segments with specific overall density 2012-10-02 12:57:24 +00:00

Martin Diehl 6301787df4 moved the the variable cutBack from FEsolving.f90 (where it was not used at all) to the interface routines to make responsibility of cut back control clear
PLEASE RUN setup_code.py IF YOU DO MARC SIMULATIONS, THE INTERFACE HAS CHANGED
2012-10-02 12:46:58 +00:00
Martin Diehl c8b7da432c set debug_level to be protected as it is read-only for other modules 2012-10-02 09:35:39 +00:00

Franz Roters 9fc46b4950 added /echo/ statements 2012-10-02 08:12:53 +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

Christoph Kords 8336d0705c new numerics parameter "unitlength" that scales the model size in DAMASK; this enables to use very small models in marc without getting any numerical problems for example with contact which does not seem to work when using very small numbers 2012-09-24 06:13:26 +00:00
Martin Diehl b587bffdd5 added some 'protected' statements to variables that shouldn't be changed by other modules 2012-09-22 16:49:41 +00:00

Christoph Kords f153866030 introduced factor to control edge contribution to multiplication;
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
Christoph Kords d80b45c1d9 added relativistic correction of velocity (maximum velocity given by parameter in material.config); probability of thermal activation in velocity law not allowed to be greater than one.
output of creation rate for edge jogs now for own system, not collinear.
check for negative densities in dotState now uses absoluteToleranceRho instead of significantRho.
2012-08-30 07:33:13 +00:00
Martin Diehl 8e3b547cbd changed numerics.f90 back to the old openmp statement as this doesn't seem to cause the problem and is standard conforming
corrected typo in constitutive_j2.f90 that might cause abaqus to crash
now running 20 tests of abaqus in order to have a decent statistic about the crash behavior
improved abaqus_v6.env
2012-08-29 16:16:10 +00:00
Martin Diehl 84e3f94424 added flush for easier debugging 2012-08-29 15:23:43 +00:00

Martin Diehl d089c12947 abaqus seems to have similar problems with the openmp lib as marc (use module vs. include file), i hope this fixes the crashes 2012-08-28 19:48:38 +00:00
Martin Diehl 5e9e8497e6 new solver is now compiling without a PETSc installation, however only the plain basic solver is available then.

2012-08-28 19:19:47 +00:00
Martin Diehl 0f64289d75 fixed bug causing trouble with ifort 11 (abaqus) 2012-08-28 19:10:54 +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
2012-08-28 16:08:17 +00:00

Martin Diehl 96ba5ecae4 moved some more 'mesh related' functions for post processing from math.f90 to mesh.f90
f2py functions remaining in math.f90 now uses assumed size arrays in order to have simpler interfaces. This is only working with python 2.7!
changed python pre- and postprocessing scripts.
If you encounter any problems whith core modules, try to remove the old core.so in the lib/damask
2012-08-27 08:04:47 +00:00

Christoph Kords 3cd5fa90e8 corrected dislocation multiplication term for special case of zero density 2012-08-24 11:36:46 +00:00
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"
2012-08-21 08:53:36 +00:00
Martin Diehl 35dffd52c1 now using spectral_quit (like old spectal solver, needed because of f2py) 2012-08-20 13:22:34 +00:00
Martin Diehl b96df9987e fixed reading/writing of integer arrays with function for real arrays 2012-08-16 14:55:23 +00:00
Martin Diehl 453c6031a7 added functions for reading values of integer data type to binary file, corrected comment on old versions which are for real (pReal) only 2012-08-16 11:57:15 +00:00
Christoph Kords b2aacf9ca4 rates in constitutive_results are taken directly from last converged step and not calculated again; added output of rates for annihilation of screws and deposition of edge jogs on collinear system 2012-08-16 11:03:22 +00:00
Christoph Kords bd754dbefd corrected debug output of evolution rates; added possibility to change the safety factor for the CFL flux condition via the material.config file; updated the example material.config due to recent changes in nonlocal constitutive 2012-08-16 09:13:38 +00:00

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
Pratheek Shanthraj 259eb7850e more work on array ordering in new solver. (now working but not tested) 2012-08-10 17:01:58 +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

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). Also remobilization of dead dislocations at neighbor is taken into account for flux. 2012-03-14 15:32:50 +00:00
