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.

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

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
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.

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.

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

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

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

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.
