Christoph Kords 314ca3fe7f Internal stress calculation in nonlocal model: instead of integration of excess gradients (->Bayley) we now sum up contributions from adjacent superdislocations within a certain radius R. When periodicity is used, also periodic images are considered in stress evaluation. 2011-03-29 07:34:33 +00:00
Christoph Kords 3d51dd36fa * Introduced preprocessor directives in order to suppress compilation of most write statements when using openmp. This tremendously improves efficiency of parallelization.
* Also added some more openmp directives to increase percentage of parallelized code.

* "implicit none" was missing in two subroutines of homogenization and constitutive.

Christoph Kords b8b75edd7d no changes to previous version, just wanted to add some comment to the previous commit:
subroutine "constitutive_nonlocal_dotState" only affects the current dotState, so no need to pass the whole array as argument
2011-03-21 15:23:36 +00:00
Christoph Kords 9b1e1e35ea dotState 2011-03-21 15:18:09 +00:00
Christoph Kords 462eda6736 split parallel region in integrateStateFPI into two 2011-03-21 14:30:10 +00:00
Christoph Kords 5ee73dee72 age dotState before resetting it to zero, otherwise the statedamping does not work. 2011-03-21 13:06:11 +00:00
Christoph Kords fc6f2ae68f No need to call constitutive_microstructure at the beginning of each crystallite step, since it's already been done at the end of the previous step. Just do it once after initialization to start with correct values for the dependent state variables. 2011-03-21 10:35:42 +00:00
Christoph Kords 11138e3ee2 debugging output is now controlled by the "verbosity" parameter in the debug.config ranging from 0 (=almost no output) to 8 (=very detailed output)
0 : only version infos and all from "hypela2"/"umat"
1 : basic outputs from "CPFEM.f90", basic output from initialization routines, debug_info
2 : extensive outputs from "CPFEM.f90", extensive output from initialization routines
3 : basic outputs from "homogenization.f90"
4 : extensive outputs from "homogenization.f90"
5 : basic outputs from "crystallite.f90"
6 : extensive outputs from "crystallite.f90"
7 : basic outputs from the constitutive files 
8 : extensive outputs from the constitutive files

If verbosity is equal to zero, all counters in debug are not set during calculation (e.g. debug_StressLoopDistribution or debug_cumDotStateTicks). This might speed up parallel calculation, because all these need critical statements which extremely slow down parallel computation.
2011-03-21 10:31:17 +00:00
Christoph Kords 9d7ede7e03 extreme values of stress and jacobian now recorded in CPFEM_general. variable declaration and generation of output moved to debug module. 2011-03-17 13:13:13 +00:00
Christoph Kords 235266b169 openmp parallelization working again (at least for j2 and nonlocal constitutive model).
In order to keep it like that, please follow these simple rules:

DON'T use implicit array subscripts:
example:    real, dimension(3,3) :: A,B
                  A(:,2) = B(:,1)               <--- DON'T USE
                  A(1:3,2) = B(1:3,1)       <--- BETTER USE
In many cases the use of explicit array subscripts is inevitable for parallelization. Additionally, it is an easy means to  prevent memory leaks.

Enclose all write statements with the following:
!$OMP CRITICAL (write2out)
<your write statement>
!$OMP END CRITICAL (write2out)

Whenever you change something in the code and are not sure if it affects parallelization and leads to nonconforming behavior, please ask me and/or Franz to check this.

Franz Roters 97a0146672 deactivated one debug statement at the end of crystallite_updateState(g,i,e) as it leads to division by zero if constitutive_state(g,i,e)%p(1:mySize) contains zero values
statement should be changed to check for zero values
2011-03-11 10:05:30 +00:00

Franz Roters 18e668340f Abaqus interfaces dapted to newest version of the rest of the code
does not yet check for restart, have to check out first how restarts work in Abaqus
explicit code not checked as we do not have a license
2011-03-07 12:49:27 +00:00
Franz Roters 654b5ea987 set type for acos_arg 2011-03-04 14:57:22 +00:00

Franz Roters 6667e94238 abaqus routines VGETOUTDIR and GETOUTDIR do not return the trailing slash, which we assume to be there, so it has to be appended 2011-03-03 10:29:59 +00:00
Martin Diehl 138e9c43eb some comments (talking to Ricardo) 2011-02-25 16:24:23 +00:00
Martin Diehl a6d1e5c911 now deleted old _single files 2011-02-25 12:49:18 +00:00
Martin Diehl 8cae4d609a 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
Christoph Kords ad4706673b * 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
Martin Diehl cd5407b08b 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
Christoph Kords 2f503f5cdb added "Lp" as crystallite output 2011-02-25 08:15:26 +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
2011-02-24 18:39:57 +00:00
Christoph Kords e49e5e13af * 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
Christoph Kords 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
Christoph Kords 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 2011-02-23 12:33:51 +00:00
Christoph Kords 430966eb20 sorry, forgot to commit the numerics.f90, too 2011-02-23 12:30:52 +00:00
Christoph Kords 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
Christoph Kords 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
Martin Diehl 8dd1a694a3 extended IO to cope with different name for solverJob and Model
polishing, added error codes
added FFTW library files
2011-02-21 14:37:38 +00:00
Christoph Kords b21c153761 restructured constitutive_nonlocal_compatibility and incorporated the "surfaceTransmissivity" in the compatibility calculation 2011-02-16 16:38:18 +00:00
Christoph Kords 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
Christoph Kords 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!!!
