Christoph Kords daf89806b1 fixed bug in deltaState; used to lead to unpredictable values in accumulated shear, since deltaState was not defined at this state position 2013-06-11 21:03:23 +00:00
Martin Diehl 296a5040b9 fixed bug in initialization when reading in material.config.
Fortran does not short-circuit, e.g. (if a>0 .and. b(a) ==c) might cause an out-of-bounds error when a=-1 it'll try to access b(-1)!

Christoph Kords 6fac7c347c fixed bug in constitutive_nonlocal_kinetics that was introduced in rev2088 along with the non-Schmid behavior: nonSchmid matrix of last slip system was used for all slip systems; led to extremely bad convergence due to flawed dLp_dT 2013-05-10 22:29:12 +00:00
Christoph Kords d9cc42daef slight change in flux formulation: no flux to neighbor, not only if there is a sign change in the velocity, but also if the neighboring velocity is exactly zero 2013-05-10 08:42:42 +00:00
Martin Diehl b2a3c9235b fixed some warnings issued by gfortran (type conversion, not needed use statements) 2013-05-08 09:23:47 +00:00
Christoph Kords 6e64b5c476 better not allow for deads to contribute to flux, since not clear at which interface they got stuck 2013-05-07 18:47:17 +00:00
Christoph Kords a7706090d2 neighborhood relations were screwed up for some elementtypes as of version 2318, might have caused segmentation faults with nonlocal model, now fixed 2013-04-22 13:35:35 +00:00
Christoph Kords ad879ebcf9 forgot to delete all occurrences of obsolete "constitutive_nonlocal_ accumulatedShear" in last commit 2013-04-08 08:51:12 +00:00
Christoph Kords 10e50bf41d improved accuracy of "accumulated shear": now added as a state variable, which facilitates integration (dotstate=shearrate); needs absolute tolerance value for state integration in material.config 2013-04-04 13:37:14 +00:00
Christoph Kords 3c25723139 - make sure that formerly blocked density is not able to move to neighbor until it is remobilized
- added some explicit indices instead of ":"
2013-04-03 16:29:48 +00:00
Christoph Kords 6d3f05b387 small changes in nonlocal constitutive model:
- make sure neighboring density is always greater equal zero
- no extra Bauschinger in postResults
2013-04-03 16:22:55 +00:00
Christoph Kords b8f8d66f82 total density used in backstress calculation now based on average of neighborhood
fixed small bug in state_init: random distribution of density was probably not working correctly, as some variables were not properly initialized
2013-03-27 13:04:01 +00:00
Christoph Kords 19655c2d92 significantRho check was flawed for dipole density 2013-03-25 17:36:04 +00:00
Franz Roters 02f092492e updated copyright header 2013-03-22 17:35:05 +00:00
Christoph Kords cee90bbdb3 simplified dislocation kinetics: dropped relativistic correction of velocity, since the infinite attack frequency already sets a limit for the velocity; dropped second; also dropped the correction term for backward jumps, since it was probably not meaningful 2013-03-21 12:52:29 +00:00
Pratheek Shanthraj 07ff1f7c93 reporting current time for most module inits 2013-02-25 16:34:59 +00:00
Philip Eisenlohr c1cf446774 parsing of material.config file now expects adequate number of (slip/twin) family entries according to given lattice type.
used to read up to maxN, but that caused unnecessary IO_warnings...
2013-02-14 22:24:55 +00:00
Martin Diehl f0b4281400 removed unused variables, added pure statements, and declared external functions as external (using gfortrans debug option) 2013-02-11 10:43:45 +00:00
Mahesh Balasubramaniam 362cbf3359 Made corresponding changes in the constitutive files and DAMASK_spectral_driver and interface files with respect to the changes made to IO.f90 2013-02-06 16:45:34 +00:00
Martin Diehl 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

Pratheek Shanthraj fd94c786f0 moved stiffness tensor calculation to lattice
introduced 'isotropic' and 'orthorhombic' lattice types to use corresponding symmetries in stiffness tensor. intended to be used with non-crystal plasticity models (j2, constitutive_none with isotropic, cubic or orthotropic elasticity).
