Luc Hantcherli d8ce85c033 Syntax corrections. Update of constitutive.pheno and constitutive.dislo. 2007-10-16 11:30:05 +00:00
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.

Franz Roters 532d3c2a16 added use crystal statement before call of crystal_init 2007-10-15 10:16:51 +00:00

Franz Roters 28fc9cc221 put recalculation of elastic stress back in (was accidentally deleted)
changed check of residuum improvement for small residuum
2007-08-13 07:12:24 +00:00
Franz Roters 85df3b95ee changed restriction of dTstar, its now based on the residuum, if it does not improve 0.5*dTstar is used instead 2007-08-07 08:02:31 +00:00
Franz Roters a5f49a0578 changed first elastic guess for small Tstar
changed residuum to only consider deviatoric part of Tstar
changed scaling when dTstar becomes too large to proportionally scaling all components of dTstar
2007-07-20 13:32:44 +00:00
Franz Roters a1c3df84ab changed quite a few things, mainly using last result as initial guess now, thinks work a lot better now but still not perfect 2007-06-06 14:38:06 +00:00
Franz Roters 49886a072c corrected CPFEM_stressIP to use FFN1 at the end of the time increment
calculate for ncycle==0 and not only inc==0 in hypela2
2007-05-14 12:13:36 +00:00
Franz Roters 033a6a03b3 determine number of grains as texture_Ngrains(mesh_element(4,cp_en)) instead of constitutive_Ngrains (which is not used anymore) in CPFEM_stressIP 2007-04-25 13:58:10 +00:00
Franz Roters 3a4ec4c2d1 removed several unused variables 2007-04-24 06:49:13 +00:00
Philip Eisenlohr 471d53e3ba _general needs CPFEM_en NOT cp_en..!
stress loop counter was not been reset
matmul(A,B) now replaced by stored AB
