Christoph Kords b72d75ed05 corrected indices in flux density output 2011-01-28 12:49:58 +00:00
Philip Eisenlohr 0cf1404db0 changed from element 117 (hexahedral with reduced integration) to element 7 (hexahedral with full integration). one-IP elements give trouble in the ping-pong scheme by being frequently/always outdated. this is likely connected to their finite element technology such that even high stiffness values do not prevent the solver from altering displacements in subsequent cycles. remedy is to go for full integration combined with /elementhomogeneous/ phase... 2011-01-27 14:32:29 +00:00
Philip Eisenlohr c00a42a9a4 fixed last remaining tensor outputs to their transposed versions 2011-01-27 14:29:06 +00:00

2011-01-26 12:56:52 +00:00
Christoph Kords 05d4d5fef2 * kinetics now according to Mohles; enables solid solution hardening

2011-01-26 10:17:42 +00:00
Philip Eisenlohr 6ac06af517 sorry, forgot to alter the most important part: post_results..! eventually, the t16 has defgrads and friends in correct format: du_i/dx_j is listed as linear array (1,1),(1,2),(1,3),(2,1),... 2011-01-24 16:23:37 +00:00
Philip Eisenlohr 38409ebc71 included both new voronoi_xxx scripts 2011-01-24 16:21:49 +00:00
Philip Eisenlohr ee7a8ad52a general speed up
spectral format records physical coordinates
tessellation now based on phys coords instead of discretization.
2011-01-24 16:21:17 +00:00
Philip Eisenlohr 4ee40df5ba transposed writing into t16 file (and screen/debug) did not work with just stating array(1:3,:)...
fixed by using math_transpose3x3 (and similar) instead.
2011-01-24 15:02:19 +00:00
Philip Eisenlohr 794aeb253b crystallite and CPFEM now print/output tensors in ij notation (used to be, particularly in the t16, ji, i.e. transposed...)
math reports random seed used for rnd() generation
2011-01-20 19:25:45 +00:00
Philip Eisenlohr e721f2b654 sight restructuring of algorithm -- same functionality 2011-01-20 19:22:22 +00:00
Martin Diehl 52f06009be rewrote voronoi tessellation. the VE generation is now divided into two parts:
-generation of random positions (in a 1x1x1 parameter space) and random angels
-actual voronoi tessellation
for the generation of the positions, a resolution can be specified to ensure that the tessellation works at that resolution. The tessellation will always work on larger resolutions but not necessarily at smaller ones.

* added missing error codes
2011-01-12 12:36:48 +00:00
Christoph Kords d92f992eb7 if nonlocal ip has local neighbor assume perfect transparency of the (perhaps virtual) phase boundary. this is only a quick fix! need to rethink the way constitutive and real boundaries are treated! 2011-01-11 18:00:29 +00:00
Christoph Kords 6a3dd78259 fluxes are disabled when keyword "/nonlocal/" is omitted in the material.config (this is a way to use the constitutive_nonlocal model as a local dislocation based model) 2011-01-11 14:55:36 +00:00
Martin Diehl 322cbd2597 changed tools for voronoi tessellation to match new specification (file extension and resolution). Also renamed the files, because the space characters cause trouble
improved reconstruct.f90 and spectral_post.py, both files work now under linux

added make_reconstruct.py, small shell script for using f2py
2011-01-07 14:37:05 +00:00
Martin Diehl ccc6aac10b did not delete mpie_spectral2.f90 properly 2011-01-07 13:11:32 +00:00
Martin Diehl 71fb5eedf2 changed makefile: material subroutines are now compiled using openmp, enabled linux threads for fftw3 (also did some slight changes to enable that in the fortran source code)
renamed mpie_spectral2.f90 to mpie_spectral2d.f90 (testing file, not properly working at the moment)
changed file extension and variable names in mpie_spectral.f90 and mpie_spectral_interface.f90 from "mesh" to "geom". Removed direct output from mpie_spectral.f90, all output is now base on materialpoint_results(:,1,:)

Franz Roters 9447330ab0 ATTENTION repository has been moved to new server!
Now at musvn1:/home/svn/repos/cpfem
2011-01-05 16:11:51 +00:00
Martin Diehl 20c00288b8 ---had some problems with svn, hope everything is ok now---
added new tools to generate colormaps for paraview and gmsh, written in python
removed old fortran colormap generator.

removed test.py (not longer needed) and the python module reconstruct.pyd (not running under linux)
2011-01-05 14:53:31 +00:00
Martin Diehl 3b0eeb9956 added files for geometry reconstruction from given deformation gradient.
reconstruct.f90 is a fortran source file with comments to use with f2py
reconstruct.pyd is the compiled python module

test.py is a test file to check if the reconstruction works (unfortunately i does not at the moment, probably because there are type conflicts between fortran and python)

number of threads is now written to *.out file
2010-12-02 11:04:29 +00:00
Martin Diehl ab82dbc99c continued working on reading header of output file 2010-11-30 14:26:30 +00:00

Denny Tjahjanto 36f27edd75 1. Adding more comments
2. Changing 'subroutine' into 'function' for optimizing the computation time
2010-11-26 11:50:20 +00:00
Christoph Kords 6b199e7830 allow 2digit values to be read in for MPIE_NUM_THREADS 2010-11-25 10:34:55 +00:00
Franz Roters 4216a3e066 corrected name of include file 2010-11-24 07:55:08 +00:00
Franz Roters c07a91d19e removed -save option from the compile statement using OpenMP 2010-11-23 16:25:58 +00:00
Christoph Kords ea6a6c9503 * environment variable MPIE_NUM_THREADS now determines number of threads used in parallel regions
* default value of the OMP_NUM_THREADS variable has to be restored at the end of mpie subroutine, since marc also seems to use and change(!) this 
* usage: "export MPIE_NUM_THREADS=<number of threads>" to set variable in shell, then restart mentat and compile with option 3 (at the moment this does only work on ws 6, since all other workstations use compiler option "-save"; this puts all local variables by default in static memory, which is a killer for parallelization!)
2010-11-19 17:45:27 +00:00
Christoph Kords b9b226548c * enclose wall time measurement for LpAndItsTangent and count of leapfrogbreaks by CRITICAL construct
* better use SINGLE (having an implicit barrier at the end) instead of MASTER construct
* deleted all explicit BARRIERs after do loops since parallel loop construct implies barrier at the end
2010-11-19 17:29:29 +00:00
Christoph Kords 15728d3305 enclose wall time measurement for dotState and dotTemperature function by CRITICAL construct 2010-11-19 17:19:03 +00:00
Philip Eisenlohr b2cc34349f corrected mistake in nodeCoordinate assignment, bug-fix for option " --filter 'x,y,z' " 2010-11-12 08:56:04 +00:00
Christoph Kords 4f267f4375 parallelization now works properly (not yet tested extensively though):
* had to add some BARRIER constructs
* only the master thread is allowed to increase the state counter

yet parallelization seems not to give a significant decrease in calculation time with nonlocal model (because of too many CRITICAL statements?)
2010-11-11 16:16:05 +00:00
Christoph Kords 14594dc9e2 * OpenMP does not like unbounded array subscripts in function calls
* some write statements were still not enclosed by CRITICAL construct, some needed a MASTER construct
2010-11-11 13:14:53 +00:00
Philip Eisenlohr f3a7e323ea pretty printing of hex slip/twin systems 2010-11-09 13:20:33 +00:00
Christoph Kords bca951325d * cpfem will now produce a warning if all components of the stiffness tensor are close to zero 2010-11-04 18:18:01 +00:00
Philip Eisenlohr 54748bb6a5 cycleCounter reset was 0 now -1 ==> occurence of jacobian calculation is now correct, i.e. always calc at start of new increment 2010-11-04 18:15:50 +00:00
Philip Eisenlohr e561358a90 presentation to illustrate Marc/Mentat interface for restarting capability (thx to Denny!) 2010-11-04 15:31:29 +00:00
Christoph Kords 405d5529e7 * checked and corrected parallelization of code. compiles now successfully, but simply aborts computation with first parallel directive without any comment :-(((
* also put a call to constitutive_microstructure at the start of each crystallite_integration subroutine like it was before. need that for nonlocal model in case of crystallite cutback
2010-11-03 17:22:48 +00:00
Philip Eisenlohr 0dd99cb965 lattice: (re)introduced _symmetryType function to replace unsafe lookup array
numerics: polishing

mpie_cpfem_marc: polishing

..powerlaw: aware of symmetryType function

crystallite: aware of symmetryType function, smaller leapfrog acceleration

IO: new warning 101

CPFEM: range of odd stress is now -1e15...+1e15, H_sym is used for stiffness

Denny Tjahjanto 763c20b302 Introducing the capability to restart jobs that crashed in the middle of sims. At the moment, this feature is exclusive for Marc.
Major changes:

CPFEM.f90 => 
1. Moving the initialization out of CPFEM_general into a separate subroutine, which is directly called by the hypela2 (Beware, the Abaqus version must also be modified in order to adapt with this change).
2. Restore primary state variables in CPFEM_init from binary files when requested (Marc flag: restart read).
3. Writing primary state variables into binary files (Marc flag: restart write).

FEsolving.f90 =>
1. Adding functions to recognize Marc restart flags: read and write and the corresponding restart file (parent job).
2. Change the initial value of cycleCounter = -1 in conjuction with the change made the ping-pong scheme

homogenization_RGC.f90 =>
1. Just syntax polishing.

IO.f90 =>
1. Adding functions/subroutines to open binary files for writing the primary state variables for restart purpose.

mpie_cpfem_marc.f90

1. Modification of the general scheme for collection and calculation in order to accommodate the newly added restart feature.
