Pratheek Shanthraj 639ca89133 DAMASK (except nonlocal) now sees and interacts with FEM solver 2014-06-06 00:38:29 +00:00
Martin Diehl e62c5fdc05 added consistency check in material.f90: Microstructure index in geometry must not exceed number of sections in material.config
better error messages in case of recursive file input in IO.f90. also supports absolute path now
2014-05-15 09:40:43 +00:00
Martin Diehl 01416b7ab6 set num threads back and forth between abaqus and DAMASK (like marc) 2014-04-29 16:11:13 +00:00
Martin Diehl 84ce6e429a changed handling of non-converged BVP solution: By default, exit if no solution is found to prevent "user errors"
Removed ambiguous "regridMode" keyword which was used to trigger this behavior in favor of  "continueCalculation", Set this to 1 to get back old behavior, e.g. report non-converged increments.

Martin Diehl 4bb5439994 removed copyright from *.f90 and *.f files, will be added using the deployMe script for release/nightly build. Now based on presence of svn:keywords property set (usually "Id"). Similar thing will be done for .py, .sh, and .config files but more involved because they might be executable 2014-03-29 08:20:36 +00:00
Martin Diehl b9722b866c improved error handling when getting number of threads 2014-02-28 10:30:07 +00:00
Martin Diehl bc4cc20c55 slightly polished makefile and numerics, recompile fftw with icc; still not running with ifort 14.01 2014-02-06 10:41:34 +00:00
Martin Diehl 7885ebaf8f added 'reset' flag for recursive function IO_read, need to reset stack when stopping exectution (will be used by constitutive and homogenization) 2013-12-11 16:49:20 +00:00
Martin Diehl dc95c82d4a removed temperature integration and corresponding data structures and debugging options
temperature is stored in crystallite, but homogeneous on one IP (not an component (grain) quantity and an input value parsed in by the BVP solver.
introduced heat, a component (grain) quantity which is homogenized before returned to the heat transfer solver.
went ahead with removal of dummy functions in homogenization and constitutive, this time mainly reduced function signatures to reflect actually needed quantities.

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

Martin Diehl d2ae06015a moved "Random is random" to output of random seed, cleaned up a little 2013-03-28 10:02:11 +00:00
Martin Diehl 15b6242585 set more appropriate default values for spectral solver tolerances (abs stress BC was at huge()) 2013-03-26 16:36:52 +00:00
Martin Diehl e6f6c22a30 polished Abaqus Standard, changed inclusion of OMP functionality from "spectral style" (include) to "marc style" (use) to prevent explicit from crashing 2013-03-25 18:25:15 +00:00
Franz Roters 02f092492e updated copyright header 2013-03-22 17:35:05 +00:00
Martin Diehl dd06d07e1c set default number of iteration for spectral solver to 250 instead of 40, abaqus doxygen now does the correct inclusion (everything appeared twice before) 2013-03-14 23:10:02 +00:00
Martin Diehl 1779510dda remove some unused variables, set default value for divergence calculation to 1.e-5 and made calculation independent of dim and res 2013-03-12 18:48:28 +00:00
Pratheek Shanthraj 0209a1d5a7 restructured AL solver to resemble polarization scheme and introduced alpha and beta parameters in numerics to determine what kind of solution you want. alpha = beta = 1 results in the AL scheme. alpha = beta = 2 results in the accelerated scheme. safe values are anything in between. changed the solver to use stress calculations on the campatible field which seems to result in faster convergence. 2013-02-28 17:35:02 +00:00
Martin Diehl 59da88460e preparation for introduction of plain mode and restructuring of calc modes for CPFEM_general 2013-02-27 20:41:14 +00:00

Martin Diehl a98be4e0cf IO_error and IO_warning crashed for string of zero length (or only containing whitespaces), fixed now.
Also added BEGIN and END statement to numerics in case of non-presen DAMASK_NUM_THREADS, would prevent this error and is better for debugging
2013-02-20 21:56:59 +00:00
Martin Diehl c7c81a5ab5 removed unused variables and declared external functions as external 2013-02-11 09:44:17 +00:00

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
2012-12-14 15:18:04 +00:00
Christoph Kords e10000a338 Introduced an alternative cutback scheme for the nonlocal model, that allows to keep the results of most of the ips that immediately converged, and only do cutbacks in regions where some ips are in big trouble. Only works for nonlocal model and state integrator 2. 2012-11-27 18:36:55 +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 d5ce49c471 numerics got some protected statements and is now reading in the new keywords for the solver selection in small letters.
