Christoph Kords 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

Martin Diehl 9927cd7adb 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

Alankar Alankar 2cc7bc38d7 Fixed a missing ','. Assigned plane and direction names. 2010-10-01 06:32:44 +00:00
Philip Eisenlohr 1ae252c1ce altered hexagonal slip systems
(needs comparison to former set, which is potentially wrong)
2010-09-30 17:31:19 +00:00
Claudio Zambaldi b85f9b0770 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. 2010-09-30 12:55:38 +00:00

Martin Diehl 6ea8623f65 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

2010-09-06 16:51:11 +00:00
Philip Eisenlohr a3c92061f9 1) terminallyIll was reset before FE did cutback --> useless extra calculations of same problem over and over...
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!)
2010-09-06 16:06:41 +00:00

Alankar Alankar 4f29e8c2fe Introduced twinning. Twinning based on accumulated shear on twin systems. No slip-twin interactions yet. 2010-09-01 10:07:52 +00:00
Martin Diehl a5c228fd02 changed back transform to complex-to-real, removed redundant variables, reduced size of arrays where possible 2010-09-01 08:05:11 +00:00
Martin Diehl 85febf0803 added fftw3 as fft(library will not versioned, should be in a linkable folder) , did some corrections on the code, splitted main file up (allows use of makefile), added makefile
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
