4bb5439994
removed copyright from *.f90 and *.f files, will be added using the deployMe script for release/nightly build. Now based on presence of svn:keywords property set (usually "Id"). Similar thing will be done for .py, .sh, and .config files but more involved because they might be executable
2014-03-29 08:20:36 +00:00
a0d75ee05e

added public statements to fftw functions and constants after whole math module is private now
2013-06-06 09:25:27 +00:00
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

2013-02-01 07:26:21 +00:00
e74b5da19a
changed all remaining routines to fortran-fast arrays (geometry reconstruction etc.)
...
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
093cf92338

2012-12-14 17:30:22 +00:00
1e32eb560e
corrected buggy calculation of Schmid matrix for twins introduced in rev1809.

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

4d09ef0648
changed variable name "debug_what" to "debug_level"
2012-07-05 09:54:50 +00:00
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

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).
polished and renamed the scripts for converging ang files
renamed voronoi_randomSeeding.py to spectral_randomSeeding.py
2012-03-29 19:54:31 +00:00

1330576a01
added new math function "math_deviatoric33" which returns the deviatoric part of a 3x3 tensor
...
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)
2012-01-26 13:50:00 +00:00
