-- mesh_build_subNodeCoords

Philip Eisenlohr 9d14dbde2b started to document things with the description of the "all-purpose" element 7 (or 3DC8) as interpreted by mesh.f90 2009-01-16 08:29:03 +00:00
Franz Roters 7b076185b2 This is a major update.
I restructured the subroutine in view of non local constitutive models.
ATTENTION OpenMP parallelization does not work with this version, needs some more work.
ATTENTION CPFEM_GIA8.f90 is not addopted to the new scheme and will NOT work, should actually be renamed CPFEM_RGC.f90 ;-)
I removed crystallite.f90, the routines are now in CPFEM_*.f90.
I removed the marc2005 interface routine since it is outdated.

Franz Roters e8cd7cef94 fixed a small bug: text about finding symmetric solver was always written to out-file 2008-11-27 15:11:44 +00:00
Franz Roters 824cec5ca1 correct error in case of outdated FFN1: element number is cp_en not e 2008-11-11 14:57:20 +00:00
Philip Eisenlohr db245e8935 a small text file to remember ideas for code improvement 2008-11-10 08:41:32 +00:00
Luc Hantcherli 3ec8ec6b15 New version of constitutive_dislo.f90, where some dangerous spots were reformulated.
PROBLEM: [001] in tension does not have a symmetrical change of shape, which is definitely not good at all. I checked my implementation and I really do not see any errors. Could someone check it out? Can it comes from the numerical integration?
2008-11-07 16:34:29 +00:00
Luc Hantcherli 6e13ed0566 I will proceed step by step.
constitutive_dislo.f90 contains a modified version of Anxin's dislocation based model. As far as tested it, I consider it now error free. Mechanical twinning is NOT implemented YET.
mattex.mpie file is modified in accordance with the changes in constitutive_dislo.f90
It would be a great help if someone else can check the implementation. I may have overseen something.

Franz Roters 9692f2f3d3 added mpie_cpfem_marc2008r1_sequential.f90 2008-10-30 11:18:10 +00:00
Franz Roters 1a5a68c87a added interface routine for Marc2008r1
this includes two files: concom_f90 and creeps_f90
so you either create links of that name to the new files concom2008r1 and creeps2008r1 or rename copies of those files accordingly

Philip Eisenlohr 7faaa8532c this provides adapted functionality to go with the sequential wrapper.

mode 1,2 to be directly used in the subsequent (and now FE sequential)
call to MaterialPoint.
2008-08-01 07:58:59 +00:00

2008-06-17 14:42:45 +00:00
Luc Hantcherli 434ac7f06e In dislo:
- 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
2008-06-17 14:40:46 +00:00
Franz Roters 2472de77c2 OpenMP seems to work now
watch out for critical sections
write and matmul statements need to be marked accordingly!!!
2008-06-17 13:15:36 +00:00
Philip Eisenlohr 6921c57c7d rev 225 had a small syntax error... 2008-06-17 11:54:34 +00:00

Franz Roters 60f3571266 added code lines for OpenMP, however it does not work yet! 2008-05-26 13:11:25 +00:00
Philip Eisenlohr 51e596c81d small polishing to be compatible with NAG compiler (basis for automatic differentiation) 2008-04-29 12:18:17 +00:00
Luc Hantcherli 9626c25bfb crystallite: restoration of last known good Lp_guess
CPFEM_Taylor: exit whenever cutback limit exceeded
2008-04-28 16:04:08 +00:00
Philip Eisenlohr cdb2dd8808 crystallite:
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.

Luc Hantcherli fa2d6b9b6d Make use of average consistent tangent dPdF_bar to fill eventual holes in the individual dPdF of one orientation (during consistent tangent calculation) 2008-04-11 13:04:25 +00:00

Denny Tjahjanto 9d2ce61698 A revision for CPFEM_Taylor.f90. 2008-04-10 11:22:17 +00:00
Franz Roters d2312e81ff deleted CFPFEM.f90 and crystal.f90 from repository
adopted mattex.mpie to use lattice_structure  instead of crystal_structure
2008-04-09 15:35:16 +00:00
Denny Tjahjanto 12dfbaf6b4 # separated CPFEM_Crystallite from CPFEM. Now in separate module crystallite.f90 as "SingleCrystallite"
# 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
