Franz Roters 60f3571266 added code lines for OpenMP, however it does not work yet! 2008-05-26 13:11:25 +00:00
Philip Eisenlohr 51e596c81d small polishing to be compatible with NAG compiler (basis for automatic differentiation) 2008-04-29 12:18:17 +00:00
Luc Hantcherli 9626c25bfb crystallite: restoration of last known good Lp_guess
CPFEM_Taylor: exit whenever cutback limit exceeded
2008-04-28 16:04:08 +00:00
Philip Eisenlohr cdb2dd8808 crystallite:
added full check whether residuum in inner loop is NaN
SingleCrystallite now takes/stores Lp guess

CPFEM_Taylor (missing in GIA!!):
former fully plastic guess for Lp has been exchanged by keeping the last converged Lp (global array CPFEM_Lp) to serve as new best guess for the next time step. This speeds up the inner loop of TimeIntegration.

Denny Tjahjanto 12dfbaf6b4 # separated CPFEM_Crystallite from CPFEM. Now in separate module crystallite.f90 as "SingleCrystallite"
# improved SingleCrystallite to advance by true cutbacking (instead of improving guess and integrating always from t_0)
# module "crystal" renamed to "lattice" together with its prefix for variables
# extension of "computationMode" to deal with cutbacks (CPFEM_general).
# cutback and new inc detection for MARC is based on common block variable cptim (and inc), not incsub anymore!
# generalized GrainInterAction as new homogenization scheme

# two symbolic links are required: constitutive.f90 and CPFEM.f90

Luc Hantcherli b476aa4028 CPFEM.f90 contains the following modifications:
-Temperature is now defined as a CPFEM_Temperature, and filled for each new call of CPFEM_general according the value output by MARC
-constitutive_Microstructure(state_new,CPFEM_Temperature,grain,CPFEM_in,cp_en) is used in the state loop and before entering in the stress loop. This subroutine computes all parameters,arrays or matrices required from the state, i.e. forest or parallel or mobile dislocation densities from the statistically stored dislocation densities. Its definition is made in module constitutive.
2007-10-16 08:33:59 +00:00
Luc Hantcherli ab0fddf518 Module crystal contains a so-called interaction type matrix for each crystal structure. This matrix helps for computing the hardening matrix in case of a phenomenological constitutive or the dislocation interaction intensity matrix in case of a dislocation-based constitutive.
Definition can be discuss.
