Philip Eisenlohr 2b567ad20d CPFEM
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.

Denny Tjahjanto 199c65cdba changed pert_e to new perturbation value pert_Fg 2008-02-18 10:46:18 +00:00
Philip Eisenlohr a41a4a75ef CPFEM:
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

Luc Hantcherli b8b171c95b Introduce debug module, contains distributions of nCutback, nStressLoop, and nStateLoop 2008-01-10 18:53:57 +00:00
Luc Hantcherli fe70a82d6d !!!!! IMPORTANT !!!!!
All subroutines were committed at once:
- constitutive_pheno works
- constitutive_dislo without twinning also works

This release should serve as reference

Philip Eisenlohr ad3ccf22c2 clarified tolerances in prec (abs vs rel)
all units conform to SI now !! (especially MPa --> Pa)

CONSEQUENCE: mattex files need to respect SI

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

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
Philip Eisenlohr 9da4b4cf24 name change to reflect State and Stress (was outer,inner)
added nReg for Jacobi regularization attempts
2007-04-11 10:05:08 +00:00
Philip Eisenlohr 35266bd513 added nreg to limit number of Jacobi regularizations 2007-04-10 11:22:06 +00:00
Franz Roters 4e68da3cf1 moved all numerical parameters to prec.f90
removed some unused variables

Philip Eisenlohr 4554df8625 pInz --> pInt 2007-03-20 15:58:53 +00:00
Philip Eisenlohr 80facb8b30 let's see whether this is the thing to do..!?!? 2007-03-20 13:55:22 +00:00
