Martin Diehl 06b977ff61 added public statements to fftw functions and constants after whole math module is private now 2013-06-06 09:25:27 +00:00
Christoph Kords 622e2dcf15 Fixed bug in math rotations: passive and active rotations were not clearly distinguished and partly mixed up; yet, luckily, only resulted in wrong output of euler angles.
Now fixed with following convention:
Rotation conversions do not switch implicitly from active to passive or vice versa EXCEPT when converting to or from any "Euler" type (Euler angles or Euler axis/angles). Those functions expect a passive rotation as input if converting to Euler type and return a passive rotation if converting from Euler type.
2013-06-05 19:10:37 +00:00

changed all remaining routines in f2py to more clever determination of array size (requires f2py >= 2.0)
enabled 3D visualize to work with odd resolution by switching to linear reconstruction
PLEASE NOTE: Redefinition of routines for f2py might cause trouble -> DELETE DAMASK_ROOT/lib/damask/core.so in this case
further changes: added pure statement where possible, polished, unified use of "Q" for "Quaternion" and reordered math to have similar routines together
2013-01-31 16:28:08 +00:00

2012-11-23 17:02:50 +00:00

added trace33 for matrix trace
2012-10-12 17:54:20 +00:00
Martin Diehl 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
Martin Diehl 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
Martin Diehl 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 efd1b513cf fixed bug in divergenceFDM 2012-08-27 15:43:17 +00:00

Philip Eisenlohr 4d09ef0648 changed variable name "debug_what" to "debug_level" 2012-07-05 09:54:50 +00:00
Martin Diehl 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.
2012-06-15 16:10:21 +00:00

Martin Diehl c29ae95af7 new version of AL spectral solver (seems to work, but still experimental)
new concept of DAMASK for Python: Now using also IO.f90, debug.f90 etc. instead of mimicing their necessary function. This needs DAMASK_python.f90 and DAMASK_python_interface.f90 (At the moment more or less copies of respective spectral files).

renamed some math functions, so that we have a universal naming scheme: for matrix multiplications use an "x" (e.g. math_mul33x3); don't use the "x" to describe the shape of the tensor that the function is applied to (e.g. math_invert33 instead of math_invert3x3)
