homogenization as well as constitutive are now free to choose. the runtime got somewhat longer (25% on simple tests) compared to a hardcoded isostrain homogenization. this might be a point of further optimization at a later stage...
please use homogenization_isostrain.f90 as starting point / example for future developments of homog-schemes.
the homogenization scheme now can additionally output certain results. hence, the userdata structure at each integration point now looks like this:
- sizeHomogPostResults
- block of that size containing homogPostResults
then for each grain:
- sizeGrainPostResults
- block of that size containing crystallitePostResults, which consist of:
+ phaseID
+ volFrac
+ Eulers (3)
+ any constitutive post results requested
Correction of the expression for the velocity of mobile dislocation densities in constitutive_dislobased.f90
Correction of some Fortran syntax, incompatible with Compaq Visual Fortran (e.g. integer(8))
# 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
time integration scheme changed to start from guessing of Lp.
Newton-Raphson algorithm now accelerates as long as residuum improves.
IO:
added error 650 for polar decomposition problems
prec:
some cleanup. Introduced "relevantStrain" for convergence checking in CPFEM
All subroutines were committed at once:
- constitutive_pheno works
- constitutive_dislo without twinning also works
This release should serve as reference
