IO.f90: added respecteive error message

constitutive_phenopowerlaw.f90: first test with automatic file Id

Franz Roters 4357e29e07 yet another missing "then" in homogenization 2009-08-28 15:26:18 +00:00
Franz Roters c0d1140234 added a missing "then" 2009-08-28 15:14:27 +00:00
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.
2009-08-28 15:05:14 +00:00
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

Denny Tjahjanto 644265381e mpie_cpfem_marc.f90 >>> changing the compilation sequence of modules: numerics.f90 and IO.f90 move up, while math.f90 down.
IO.f90 >>> adding "inRad" instead of using inRad from math.f90 module, since math.f90 module is now below IO.f90.

numerics.f90 >>> now can read the parameter "fixed_seed" from numerics.config. this parameter is used to set a pseudo-random number generator/fixed seeding. default value is 0 (zero), which will give fully random number.

math.f90 >> adding a possibility to fix the seeding (i.e., pseudo random number)

numerics.config >>> add a new parameter: "fixed_seed"

Denny Tjahjanto b25396374a homogenization_RGC.f90 >>> adding some lines, mostly for debugging purpose. no critical change.
constitutive_phenopowerlaw.f90 >>> adding new parameter: constitutive_phenopowerlaw_w0_slip, i.e., the hardening rate exponent.
homogenization.f90 >>> most important change is to add an if-else statement (line 379-380) to switch crystallite_requeted = .false. for already converged material point iteration (el/ip). the rest of the changes are cosmetics and debugging stuffs.
crystallite.f90 >>> similar to homogenization.f90, the most important change is to add additional if-else statement (line 574) in the jacobian (perturbation) loop. now the jacobian calculation will only be performed when crystallite_requested = .true.. the rest is only cosmetic.

Denny Tjahjanto f70013ee9b lattice.f90: correction of typo from the last update (Philip) 2009-08-26 09:02:22 +00:00
Philip Eisenlohr 7720680f3a makeMe: some polishment
lattice: found memory leak (lattice_interactionTwinSlip had wrong size) and added further commenting
2009-08-26 07:28:43 +00:00
Christoph Kords 1dbd0865db constitutive_nonlocal.f90
- completed postResults output function
- connecting vector of neighboring material points is mapped to intermediate configuration of my neighbor

crystallite.f90
- zero out dotState only when crystallite is non-finished
- set nonfinished flag to false if crystallite is not on Track after state update
- in updateState: set onTrack flag to false if encounter NaN
- removed some old debugging outputs and added others

homogenization.f90
- in debugging mode now telling when a cutback happens
2009-08-24 08:16:01 +00:00
Franz Roters 387195e036 that was tooo quick, now it works hopefully 2009-08-13 13:32:17 +00:00
Franz Roters f400cdac5b corrected paramter check for phenopowerlaw 2009-08-13 13:27:14 +00:00
Denny Tjahjanto cafc39b183 replaces Nast with Nreps in hybridIA
formerly, if the number of orientations requested was (far) less than the number of nonzero bins in the texture representation, you only got a subset of low phi1 values..! (that is the top corner in Euler space -- Hi Bing ;-) )

Franz Roters 0ef4ec27b3 there was a lonesome endif that needed a comment 2009-08-13 12:56:07 +00:00
Luc Hantcherli 93543c21e9 In crystallite_stressAndItsTangent:
state is now correctly collected during perturbation method

Denny Tjahjanto 86211bf0ce homogenization_RGC.f90: adding comments to improve clarity 2009-08-12 14:13:20 +00:00
Christoph Kords 2aae7b7574 added dislocation multiplication to dotState in constitutive_nonlocal.f90
cleaned up debugging output statements to *.out file

Franz Roters 6171361c7e terminallyIll was missing in the use statement 2009-08-12 08:10:28 +00:00
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

Denny Tjahjanto 4689966c79 correction in homogenization_RGC.f90: in the use of material module
homogenization_typeInstance was included two times in previous version.

Luc Hantcherli f0729a2e52 Cosmetic changes in constitutive_dislobased.f90
- more precise output labels
- do changes into forall
2009-07-28 10:08:13 +00:00
Franz Roters 1cd0b74b08 divide by 3.0 instead of 3 as it is _pReal 2009-07-27 09:23:39 +00:00
Philip Eisenlohr 53cff7458c polishing of constitutive output size determination in _init() 2009-07-24 15:23:45 +00:00

2009-07-24 12:02:20 +00:00
Philip Eisenlohr 97d8a321e0 some cosmetics... 2009-07-23 13:33:53 +00:00
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 290410b3fc Example of material.config, delivering the required information for the new version of constitutive_dislobased 2009-07-14 11:31:06 +00:00
Luc Hantcherli ce515beb39 THIS IS A MAJOR UPDATE
The different blocks required for the twinning model are now implemented (I guess correctly...)
Keywords in the material.config are changed. Since the flow rule for twin systems remains under investigation, this part is susceptible to further changes.
2009-07-14 11:26:52 +00:00
Luc Hantcherli d3343ef795 Corrected definition of vector n and d per deformation system; n is the system plane normal and d the corresponding direction 2009-07-14 11:20:35 +00:00

- added temperature tolerance in numerics.config
