8336d0705c
new numerics parameter "unitlength" that scales the model size in DAMASK; this enables to use very small models in marc without getting any numerical problems for example with contact which does not seem to work when using very small numbers
2012-09-24 06:13:26 +00:00
b587bffdd5
added some 'protected' statements to variables that shouldn't be changed by other modules

...
dislocation density below a single dislocation per IP considered not significant
2012-09-04 16:56:37 +00:00
22812c9a91
some minor improvement on precision detection: checking only once (in prec and no longer in math and crystallite), added one more 4/8 switch for LAPACK, as there is no single precision FFTW, stopping compilation for spectral method if FLOAT=4
...
new function in IO to print integers without leading zeros, implemented it at some places in the new spectral solver (reporting still needs some serious polishing)
updated preprocessing for documentation to handle precision correctly
2012-08-30 20:26:28 +00:00
299d9e6bc4
fixed bug in seed initialization that didn't allow to redo calculations that started with a random seed. Now the whole random seed array is set to one value, previously only the first one was reported and the remaining ones were random
...
removed old random function used by halton
2012-08-30 14:58:30 +00:00
d80b45c1d9
added relativistic correction of velocity (maximum velocity given by parameter in material.config); probability of thermal activation in velocity law not allowed to be greater than one.
...
output of creation rate for edge jogs now for own system, not collinear.
check for negative densities in dotState now uses absoluteToleranceRho instead of significantRho.
2012-08-30 07:33:13 +00:00
8e3b547cbd
changed numerics.f90 back to the old openmp statement as this doesn't seem to cause the problem and is standard conforming
...
corrected typo in constitutive_j2.f90 that might cause abaqus to crash
now running 20 tests of abaqus in order to have a decent statistic about the crash behavior
improved abaqus_v6.env
2012-08-29 16:16:10 +00:00
84e3f94424
added flush for easier debugging
2012-08-29 15:23:43 +00:00
d83150be1b
now capturing "terminallyIll" for basic solution, should end in a automatic cutback of time steps for the spectral solver
2012-08-29 05:50:42 +00:00
3106b8ce0c

d089c12947
abaqus seems to have similar problems with the openmp lib as marc (use module vs. include file), i hope this fixes the crashes
2012-08-28 19:48:38 +00:00
5e9e8497e6
new solver is now compiling without a PETSc installation, however only the plain basic solver is available then.
...
also removed reporting of PETSc related variables in the case it is not installed/found
2012-08-28 19:19:47 +00:00
0f64289d75
fixed bug causing trouble with ifort 11 (abaqus)
2012-08-28 19:10:54 +00:00
0959ff3299
substituted hand written matrix inversion by LAPACK version with precision selection.
...
also introduced check for inversion into DAMASK_spectral_Utilities.f90 for the stress BC calculation. This part is further improved by using 5% of the reference stiffness to avoid trouble in the fully plastic regime (where the stiffness is underestimated)
Test for Marc 2010 is updated because the new inversion give slightly different results near 0 (order of e-13)
2012-08-28 16:59:45 +00:00
73349d02f5
merged precision info into the file prec.f90 and removed prec_single.f90
...
precision information is now parsed as a makro, defined by the compiler, eg. -DFLOAT=8 for 8 byte long floats or -- in case no values is given -- for the FEM wrapper by the interface files.
Please don't forget to run setup_code.py !!!!!!!!!!!
abaqus_v6.env is adjusted to specify the standard precision (float=8, int=4) and got some extra compilation options, some deprecated warning supressors are removed
Optional Marc modification will follow that allow automatic selection of suitable precision
2012-08-28 16:08:17 +00:00

96ba5ecae4
moved some more 'mesh related' functions for post processing from math.f90 to mesh.f90
...
f2py functions remaining in math.f90 now uses assumed size arrays in order to have simpler interfaces. This is only working with python 2.7!
changed python pre- and postprocessing scripts.
If you encounter any problems whith core modules, try to remove the old core.so in the lib/damask
2012-08-27 08:04:47 +00:00

2012-08-24 11:36:46 +00:00
4f67d04c69
new parameter "significantRho" for nonlocal constitutive law ; density below this value will hardly contribute to dislocation glide or any dislocation reaction ; old parameter "absoluteToleranceRho" is now used only for its initial purpose, namely the absolute tolerance in the state integration
2012-08-23 05:48:21 +00:00
222aed9f60
derivative of velocity with respect to resolved stress was flawed; now much better convergence of stress integration for nonlocal constitutive law
2012-08-21 14:40:01 +00:00
ad7381cfdd
maximum relative step length in stress integration cannot decrease below 1

2012-08-20 13:22:34 +00:00
b96df9987e
fixed reading/writing of integer arrays with function for real arrays
2012-08-16 14:55:23 +00:00
453c6031a7

2012-08-16 11:57:15 +00:00
b2aacf9ca4
rates in constitutive_results are taken directly from last converged step and not calculated again; added output of rates for annihilation of screws and deposition of edge jogs on collinear system
2012-08-16 11:03:22 +00:00

...
some bug fixes
2012-08-14 16:58:23 +00:00
f5e7d576f1
introduced annihilation of screw dipoles; so far no thermal activation, but immediate annihilation; each annihilated screw dipole leaves behind an edge jog of same length as the dipole height on the collinear system
2012-08-14 12:26:20 +00:00
c1c5941733
stressAndItsTangent:
...
when winding forward to last substep in increment, also do the calculation if this substep is below "subStepMinCryst";
output of "wind forward" and "cutback" info only for crystallites that are still "todo"
integrateStress:
maximum component in Lp determines absolute convergence criterium:
aTol = max(maxLpComp * rTol_fromConfig , aTol_fromConfig)
this ensures that small values in Lp do not spoil the convergence, similar to the effect of the relevantStrain parameter before (not needed anymore in the stress integration)
2012-08-14 12:07:59 +00:00
eae9a34c6b
corrected debugging output: extreme values of returned stress and jacobian belong to cpfem debugging, not homogenization

commented-out currently unused PETSC parts.

b4103b205d
parts of the material.config can now be set to echo their content back into the log-file (i.e. STDOUT / unit 6)

b2fd3e1180
introduced preprocessor identifiers Marc, Abaqus, and Spectral to enable conditional compilation. This allows deleted dummy functions that are used by one solver only.
...
Mainly affected modules are IO and mesh. Most of the changes in mesh result from reordering the functions when grouping them depending on their solver.
Further advantage is that FE solver do not need FFTW and kdtree2 anymore. The include files for these two libraries moved to DAMASKROO/lib now as I figured out how to use a include path in the Makefile.
Put all the files I got when testing compilation with abaqus in a folder which to become the abaqus compilation test.
