first cut back is tried if material point model oder BVP solver does not converge.
If no regridding is enabled after max cut back, in case of non-converged material point the simulation stops and in case of non-converged BVP solver it continues.
set regridMode to 2 to enable regridding if BVP solver OR materialPoint model do not converge,
set regridMode to 1 to enable regridding if materialPoint model do not converge, non-converged BVP solver will be ignored as in the standard case.
For regridding, the load case need to have a restart freq set.

switched element library to geomType based.

60438cdbcc
criterion for crystallite cutback loop changed from crystallite_subStep to crystallite_todo; this avoids problems when the last substep of the crystallite increment is below subStepMinCryst (which is allowed during last wind forward)
...
fixed bug in the adaptive Euler integrator and the RK4 integrator, which could not reach the stateJump function, because of erroneous check for converged flag; also corrected the state counter for the RK4 integrator

fixed bug in crystallite_FPI: stateDamper always has to be defined for each grain
...
added some OMP FLUSH statements were necessary
replaced openmp do by forall construct where possible; this is much safer and perhaps even as fast for small loops

some small changes in including PETSc *.h90 files to prevent warnings.
...
It seems that a bug in old gfortran 4.5.0 causes the problems, at least with 4.7.3 it seems to work after fixing the bugs in IO.f90

bb033c5fe7
Simplified algorithm of crystallite_integrateStress while preserving (almost) same functionality.
...
Removed "leapfrogging" (increase of step for next guess, when last guess was ok); Replaced Armijo rule testing for step size by simple check if the residuum got better, since the former virtually did not have any effect; consistently using the 2-norm of the residuum rather than infinity-norm for the convergence check throughout the function
2012-11-06 12:35:45 +00:00

switched saturation behavior!!
...
was \dot s_alpha = (1-s_alpha/s_inf)^a h_alphabeta \dot gamma_beta
now \dot s_alpha = h_alphabeta (1-s_beta/s_inf)^a \dot gamma_beta
current form is consistent with the genmat implementation (and appears to make more physical sense). Kalidindi_etal1992 suggested this form, but altered it to the alpha-one in Bachu+Kalidindi1998... By now, it seems that some groups use alpha, others beta approach.
introduced two new absolute tolerance values for "shears" and "twinFrac" (default 1e-6).

In crystallite for state integrators 2 and 3: now that "stateJump" is called before integrating dotState, we have to do state = state + dotState *dt instead of state = subState0 + dotState * dt; otherwise the deltaState is lost
2012-10-22 13:34:15 +00:00
0980920b66
In crystallite: for state integrators 2 and 3 the deltaState always has to be done at the beginning of the integration, not at the end; otherwise the stiffness calculation can be completely wrong, when the state is changed after the stress integration for the central solution.
...
Also changed some debugging levels in crystallite and mainly in constitutive_nonlocal
2012-10-22 07:59:35 +00:00
3ecaa9e371
modified multiplication term in order to mimic a discrete distribution of dislocation sources; namely, at high resolution, when there is (on average) less than one source per integration point, a random generator decides whether there is a source in the finite volume or not; if there is one, then the multiplication turns independent of the density and depends only on the velocity/volume times a scalar factor; recovers density*velocity/lambda for large finite volumes
2012-10-19 11:40:17 +00:00
36676029e1
for state integrator 2 (explicit euler) and 3 (adaptive 2nd order euler): don't do any state evolution during stiffness perturbation, but only stress integration, since for those cases the state is not restored after every perturbation step
2012-10-19 11:20:31 +00:00
