replaced FE_maxNipNeighbors with mesh_maxNipNeighbors, which is sufficient for memory allocation, since this gives the maximum of neighbors in all cp elements

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

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

better not allow for deads to contribute to flux, since not clear at which interface they got stuck

neighborhood relations were screwed up for some elementtypes as of version 2318, might have caused segmentation faults with nonlocal model, now fixed

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

small changes in nonlocal constitutive model:

total density used in backstress calculation now based on average of neighborhood

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

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

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).

e10000a338
Introduced an alternative cutback scheme for the nonlocal model, that allows to keep the results of most of the ips that immediately converged, and only do cutbacks in regions where some ips are in big trouble. Only works for nonlocal model and state integrator 2.
2012-11-27 18:36:55 +00:00

switched element library to geomType based.
...
saves to copy same geometry description for different elements that are essentially similar regarding the IP number but differ in total node count.
introduced quadratic tetrahedron (Marc element 127 -- element 157 might also work, but did not perform well in fully elastic calc so far)
2012-11-15 22:45:20 +00:00
