new scaling feature in numerics (unitlength) did not scale the reference coordinates in the first place; now this is taken care of in mesh.f90, so scaling should work properly

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

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

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

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.

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

new solver is now compiling without a PETSc installation, however only the plain basic solver is available then.

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
Martin Diehl
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

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

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

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)
