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.

# 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!

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
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.
Corresponding changes should be carried on constitutive.f90
