Philip Eisenlohr 7e78932976 renamed "mpie_cpfem_init" subroutine within mpie_interface module to more general name "mpie_interface_init" 2010-06-08 09:35:13 +00:00
Christoph Kords 3a23dc4bbd first call to hypela2 in inc 0 is done with computation mode 2 (=plain calc), but since rev. 539 the second call was done with computation mode 6 (=only return values) instead of 2. This doesnt work, because computation mode 2 might calculate stress and tangent for all materialpoints, but the mapping from lattice to current configuration is only done for the element/IP that triggers the call.
So switched back to the former order of calls which also works for marc2010:

el 1 IP 1		|	el 1 IP 2
			|
inc mode lovl	|	inc mode lovl
------------------	|	------------------
0       2       6	|	0	2	6
1       6	4	|	1	6	4
1	4	6	|	1	3	6
1	6	4	|	1	6	4
1	1	6	|	1	2	6

Still to be checked:
according to Franz the lovl order could be different in contact analysis (e.g. starting with lovl 4 instead of 6)

Philip Eisenlohr b5fc0a9769 small rearrangement of cutback dealings. may give minute speed improvement... 2009-10-19 12:46:02 +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 0a34da292e # no need for materialpoint_results in hypela2
# homogenization updated to be compatible with abaqus interface

Luc Hantcherli ca1c61bf98 Changed constitutive_dislobased into constitutive_dislotwin 2009-10-12 16:44:17 +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...

Luc Hantcherli bc5a408c1a Changed constitutive_dislobased into constitutive_dislotwin:
in constitutive.90
in constitutive_dislotwin.f90
in mpie_cpfem_marc.f90

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"

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

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

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
