* in nonlocal model: dislocation flux now with valid description also for large angle grain boundaries; transfer of dislocations from one slip system to the other according to new variable "constitutive_nonlocal_compatibility" which depends on the angle between slip plane normals and slip directions and is updated once per cycle in function "crystallite_orientations"
...
* reactivated debugging functionality for "non-standard" integration methods

allocation of special state variables for "non-standard integration" was erroneous. used to produce segmentation fault for integration method 4 and 5.
2010-10-12 12:11:24 +00:00
fce7590c17
* now able to choose method for state integration (integrator and integratorStiffness in numerics.config); standard is "Fixed Point Iteration", which is basically the same as before; others available are "Explicit Euler", "AdaptiveEuler", "Classical Runge-Kutta" and "Runge-Kutta Cash-Karp"
...
* now remembering stiffness similar to how we do it for Lp etc.; avoids undefined stiffness values for nonconverged stiffness calculation
* non-local stuff:
* changed non-local kinetics (Gilman2002)
* enforce zero shearrate for overall carrrier density below relevant density
* enforce zero density for those states that become negative and were below relevant density before
* dislocation velocity is not limited by V^(1/3) / dt anymore

changed format of resolution. instead of reading exponent of two, now the number given equals directly to the number of FPs. Allows us to use arbitrary number of FPs.
...
example:
OLD: reading 5 results in 2^5=32 FPs
NEW: reading 33 results in 33 FPs

material.config: changed texture of microstructure 1 from 1 to 3, because 1 needs a ODF file which is not in the repository and makes the one_element_model.proc complain.

added functions math_mul33x3_complex math_Plain99to3333 to math.f90.
...
mpie_spectral.f90 uses both functions

math_mul33x3_complex is used for equilibrium check in fourier space
also did some cleaning up on mpie_spectral.f90

2) local stiffness calculation is now standard for non-local grains
3) stressLoopDistribution discriminates between (a) central solution and (b) stiffness perturbation
4) debugger is switched on as standard... (but verboseDebugger not!)

...
changes on mpie_spectral.f90:
new structure, changed variable names, now using defgrad instead of disgrad, cleaned up, removed augmented Lagrange.
ToDo: Implement Augmented Lagrange again (but then a working version), implement Large strain, think about complex-to real-transform backwards, try to implement MP-support
