A modified twin-twin interaction matrix for BCC is introduced.

An introduction of a third parameter at the interactionTwinTwin in the material.config for BCC-dislotwin materials is essential.

d9a98417ca
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)

added comments and structured the code. Temperature is not longer stored for each point but only to simplify restart behavior as long as it is not fully supported by the constitutive models

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
2012-11-08 20:00:29 +00:00

better avoid initialization of residuum_old with huge, since it posed problems in Abaqus
2012-11-08 13:26:22 +00:00
dad9922f54
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
2012-11-07 15:43:29 +00:00
bbcffa668b
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
2012-11-07 13:11:41 +00:00

preventing array index out of bounds in case of empty line, removed to goto statements

reordered PETSc initialization (now first part done in interface, setting of parameters done in numerics), removed unnecessary includes for PETSc
...
still not running with gfortran, use at own risk!
2012-11-06 16:00:51 +00:00

replaced call flush(6) by flush(6), slightly improved formating for output of gfortran version

5b6baa7c0d
introduced distinction between ip coordinates and cell center coordinates; the former can be globally calculated by subroutine mesh_build_ipCoordinates, the latter locally by the function mesh_cellCenterCoordinates; renamed mesh_ipCenterOfGravity to mesh_ipCordinates
2012-11-06 14:37:13 +00:00
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
639d6e0655
inserted missing flush(crystallite_todo) in parallel section; might have caused trouble in parallel calculations before

substituted matrix inversion to solve equation by direct solution routine from LAPACK

corrected limit for upper stable dipole distance; fixed a bug in the postResults where division by zero might happen
2012-10-29 13:02:01 +00:00
f666f8dcf3
added possibility to scale the plastic shearrate by the ratio of mobile to total density; keyword in material.config is "deadZone"

documented utilities and structured, worked on the restart capabilities of the new basic solver

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).
