abaqus routines VGETOUTDIR and GETOUTDIR do not return the trailing slash, which we assume to be there, so it has to be appended

some polishing for single precision version.
...
Now only prec and mpie_spectral are needed in different versions
2011-02-25 12:41:46 +00:00

* removed calculations for dipole formation/dissociation by stress change, since it is not used anyways; also removed associated constitutive outputs from material.config
...
* removed input variables in constitutive_collectDotState and constitutive_postResults that are not needed anymore (because of recent changes in constitutive_nonlocal)
2011-02-25 09:53:20 +00:00

removed all math functions only for double precision by the more flexible counterpart, e.g. "dsqrt --> sqrt", "dsin --> sin". Should not cause any harm, as long as "implicit none" is used.
...
Now it is possible to compile a single precision spectral solver/crystal plasticity by replacing mesh.f90 and prec.f90 with mesh_single.f90 and prec_single.f90.
For the spectral method, just call "make precision=single" instead of "make". Use "make clean" evertime you switch precision
2011-02-25 09:25:53 +00:00
2f503f5cdb
added "Lp" as crystallite output

fixed problem in internal stress calculation for periodic neighborhood
2011-02-25 08:10:11 +00:00

...
First try of implement single precision crystal plasticity, not working yet.
polishing text about geometry construction.
polishing postResults, still having problems concerning machines without MSC installation

* in flux calculation: take care of special case for single element model
...
* do not overwrite "constitutive_nonlocal_rhoDotFlux" when doing a state perturbation, so we can use it for output
2011-02-24 10:01:41 +00:00
8aef9b1c13
check for twin nodes only in direction of the surface normal. this solves a problem with models of single element thickness and periodic fluxes.
2011-02-24 09:26:30 +00:00
fed53a7e60
in subroutine "mesh_marc_get_mpieOptions": need at least one additional string after keywords "$mpie" and "periodic", not two as it used to be

sorry, forgot to commit the numerics.f90, too
2011-02-23 12:30:52 +00:00
96d3682d5e
* new global integer variable "numerics_integrationMode" (1 indicating integration of central solution, 2 indicating integration of perturbed state)
...
* combined "integrator" and "integratorStiffness" in new global variable "numerics_integrator"
2011-02-23 08:29:51 +00:00
d835380bc0
* "constitutive_nonlocal_flux" is set to zero in "constitutive_nonlocal_dotState", not in "constitutive_nonlocal_microstructure"
...
* dislocation flux and internal stress calculation now consistent with new definition of slip system lattice according to paper (polarity of screws inverted)
2011-02-23 08:08:06 +00:00
8dd1a694a3
extended IO to cope with different name for solverJob and Model

2011-02-21 14:37:38 +00:00
b21c153761
restructured constitutive_nonlocal_compatibility and incorporated the "surfaceTransmissivity" in the compatibility calculation
2011-02-16 16:38:18 +00:00
24d33bf2ff
* added a new material parameter "surfaceTransmissivity" (default value 1.0) which allows to change the transmissivity of the material surface between 0 and 1
...
* now complaining when encountering an unknown nonlocal parameter in material.config
* use same error ID for all material parameters out of bounds
* symmetric flux calculation in side dotState can now be omitted (because of new treatment of periodicity)
* switching back to "local flux balance" (add leaving and entering fluxes at central MP, don't touch neighbor) instead of "flux distribution" (subtract leaving fluxes from central MP and add them at neighboring MP). This has the advantage that there is almost no need for CRITICAL statements in parallelization, so hopefully this results in some speed up.
2011-02-16 16:35:38 +00:00
8f626c8989
Now able to have real periodicity for fluxes (fluxes leaving the model on one side enter on the other side).
...
To enable this feature one has to add the following somewhere in the marc input file:
$mpie periodic x y z
for having periodicity in all directions
$mpie periodic z x
for having periodicity in x and z direction
etc.
Note that this only works for regular meshes!!!

added ft-based reconstruction of deformed configuration to postprocessingMath.f90 and postprocessingMath.pyf
...
also added function to calculate average of tensor
some polishing in mpie_spectral.f90, added sanity check to see im resolution is power of 2

mpie_spectral.f90: changed fourier transormation, now using the advanced interface to do the tranformation both ways with just one call. now also using the same variable for pk-stress in both domains and the change of deformation gradient in both domains.
...
postprocessing: renamed name of python/f2py modul from "reconstruct" to "postprocessingMath", added some numerical operations to use for postprocessing.
2011-02-09 17:47:28 +00:00

In order to help preventing further memory leaks all array sections now have an explicit instead of assumed shape, e.g. Fe(1:3,1:3) instead of Fe(:,:).
2011-02-09 13:12:46 +00:00

* check convergence for nonlocals also in stiffness calculation mode
2011-02-09 08:39:07 +00:00

* found memory leak in nonlocal model! "constitutive_nonlocal_rhoDotFlux" has to have upper index bound of 10 for second dimension, not 8.
...
* need to recalculate dislocation velocity in postResults, otherwise we take values of last perturbed state! So the following outputs were up to now showing the perturbed state: shearrate, dislocation velocity, all density rates!

mpie_spectral and mpie_interface: changed workingdir from pathToLoadFile to pathToGeomFile

mpie_spectral and numerics: added switch to prevent pre calculation of gamma_hat. slower, but saves memory
3Dvisualize: started to add support for gmsh (not fully working yet)
reconstruct: new version of f2py/Fortran subroutines for output of results from spectral method
2011-02-07 14:35:42 +00:00
faba13f7fd
* now able to introduce some scatter in the initial single dislocation density (only for nonlocal model!) ; setting the parameter "rhoSglScatter" to a positive value generates a gauss distribution for the dislocation density with standard deviation equal to "rhoSglScatter"
...
* dislocation stress calculation is only done for nonlocal constitution ("/nonlocal/" keyword is present in material.config)

transposed writing into t16 file (and screen/debug) did not work with just stating array(1:3,:)...

crystallite and CPFEM now print/output tensors in ij notation (used to be, particularly in the t16, ji, i.e. transposed...)

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
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)

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,:)
