Philip Eisenlohr f186c83068 introduced racing condition breaker for the case of multithreaded CPFEM init. 2010-02-02 15:00:08 +00:00
Denny Tjahjanto cad278c3bc Introduce a randomness in the odd stress, using pre-factor rnd. 2009-12-09 10:33:00 +00:00
Philip Eisenlohr 992077e88e fixed cut back issue with Marc. Necessity to introduce compMode 7 to capture tangent restoration at lovl=4 call. 2009-10-17 09:25:36 +00:00
Philip Eisenlohr 21cad32137 # new interface for Abaqus
# IO has some additional functionality for Abaqus parsing
# ping pong scheme in FE interface now similar (and more human understandable) in both versions
# mesh has better splitting of different tasks, plus operation on database whenever possible
# FEsolver as new global var to indicate FEM solver type
# computation mode reshuffling: 6 is now Marc special case of recycling...

Denny Tjahjanto 3ea17dd2fd CPFEM.f90 >>> A very small, not important thing.
homogenization.f90 and crystallite.f90 >>> Correction in the algorithm to count the iteration distribution (for better statistics).

material.config and numerics.config >>> more collection of parameters.

Christoph Kords f27d66a9ae constitutive_nonlocal:
- dipole dislocations with evolution

crystallite.f90:
- collect state uses subdt and subTstar0_v
- in nonlocal modus: set all crystallites to broken if one is not on track anymore after either stress integration or state update
- constitutive_microstructure is now called inside state update and not in integrate_stress anymore

material.config:
- new parameter for nonlocal constitution

CPFEM.f90:
- age Tstar after increment was finished

Christoph Kords 8ed3ddc03b now with first draft of nonlocal constitutive law
debugging memory leak closed
debugging counters corrected

center of gravity stored in mesh

state updated is now split into a collecting loop and an execution

updateState and updateTemperature fill sequentially separate logicals and evaluate afterwards to converged

added 3x3 transposition function, norm for 3x1 matrix and 33x3 matrix multiplication in math

non-converged crystallite triggers materialpoint cutback (used to respond elastically)

non-converged materialpoint raises terminal illness which in turn renders whole FE increment useless by means of odd stress/stiffness and thus waits for FE cutback

Philip Eisenlohr f337847f35 quite some changes:
# non-greedy memory allocation
# generation of outputConstitutive to allow for script-based T16 extraction
# exchange of phenomenological by more general phenopowerlaw
# lattice is based on slip and twin families which can be treated as individual entities (switched on/off, separate hardening, etc.)
# nicer debugging output
# changed some error/warning codes
# plus potentially some minor additional brushes here and there

Luc Hantcherli 1c35103524 Corrected CPFEM: assignment of constitutive_state and _state0 consistent with homogenization_Ngrains (what is actually needed), instead of homogenization_maxMgrains 2009-07-02 08:57:35 +00:00
Luc Hantcherli 4aed2ade80 Major Update: all modules are now correctly submitted 2009-07-01 10:55:31 +00:00
Luc Hantcherli a16b8a619d Major update: corrected treatment of temperature 2009-07-01 10:29:35 +00:00
Franz Roters a6ccfe2e44 restructured the repository: renamed trunk into code, moved documentation one directory up, therefore you can now checkout either code or documentation only if you like 2009-06-25 07:17:59 +00:00
