- model for stacking fault energy computation w.r.t temperature and orientation
- classical thermodynamical approach to twin nucleation (delta_E)
- rename some parameters
In crystallite:
- add msg='ok', even if components in consistent tangent are not re-computed
- allow for pseudo-convergence in the outer-loop (case of slow convergence of dislocation densities)
in mattex:
- add new parameters
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.
# 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
renamed CPFEM_stressIP to CPFEM_MaterialPoint
renamed CPFEM_stressCrystallite to CPFEM_Crystallite
introduced new global variables to keep track of FE state within module

renamed CPFEM_stressIP to CPFEM_MaterialPoint
renamed CPFEM_stressCrystallite to CPFEM_Crystallite
introduced new global variables to keep track of FE state within module
FEsolving
changed consistent tangent scheme to D.Tjahjanto Diss version
fixed nasty bug in decision when to calculate new values (CPFEM_general)
prec
precision values should now be on safe side.
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
