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!)

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

xkdyad useful..?

looking for error calculation (Ricardo to rescue here)
2010-07-02 17:15:53 +00:00
Martin Diehl d6ba9d54b6 changed declaration of two variables from real to int, spectral method is now working.
started to commend Ricardos code, layoutet loops and removed some redundant variables.
until now, no error calculation is done. at the moment calculations are in an infinite loop

Christoph Kords 6d874e2c1f nonlocal stiffness calculation:
rather perturb all components at once (and optionally decrease the frequency of the Jacobian update with the iJaco parameter) than perturbing only a single component per cycle
2010-06-17 06:32:56 +00:00
Philip Eisenlohr 1c72439350 first shot at init with CPFEM_general
better would be to manually read the mesh resolution, set up Spectral solution strategy and call CPFEM_general just during BVP solution.
