Fixed wrong indices in tangents dT_dFe and dFe_dLp, which however luckily did not have any effect in the perturbed stiffness since they were transposed such that the double contraction of both remained unchanged.
...
In contrast, the analytical jacobian will probably be affected by this change!
@Pratheek: Can you check with me how this can be fixed?

in crystallite_integrateStress: pass full 2nd PK stress to LpAndItsTangent instead of only the deviatoric part; otherwise constitutive laws that depend on the hydrostatic pressure do not work; constitutive laws that require a deviatoric stress need to calculate it internally (as is e.g. already done in the J2 model)

removed temperature integration and corresponding data structures and debugging options
...
temperature is stored in crystallite, but homogeneous on one IP (not an component (grain) quantity and an input value parsed in by the BVP solver.
introduced heat, a component (grain) quantity which is homogenized before returned to the heat transfer solver.
went ahead with removal of dummy functions in homogenization and constitutive, this time mainly reduced function signatures to reflect actually needed quantities.

changed all remaining routines in f2py to more clever determination of array size (requires f2py >= 2.0)
enabled 3D visualize to work with odd resolution by switching to linear reconstruction
PLEASE NOTE: Redefinition of routines for f2py might cause trouble -> DELETE DAMASK_ROOT/lib/damask/core.so in this case
further changes: added pure statement where possible, polished, unified use of "Q" for "Quaternion" and reordered math to have similar routines together
2013-01-31 16:28:08 +00:00
3ffd6499b1

fd94c786f0
moved stiffness tensor calculation to lattice
...
introduced 'isotropic' and 'orthorhombic' lattice types to use corresponding symmetries in stiffness tensor. intended to be used with non-crystal plasticity models (j2, constitutive_none with isotropic, cubic or orthotropic elasticity).
2013-01-21 21:57:26 +00:00
8a45a90775
new crystallite output "grainrotationX", "grainrotationY", "grainrotationZ" that gives the deviation of the initial orientation in degrees around the sample reference x/y/z axis, while "grainrotation" still gives the same as axis angle pair in crystal coordinates

fixed bug in timesyncing procedure: if any ip that synchronizes its time step did not converge, all nonlocals become terminally ill; before, this led to an infinite loop in crystallite

Introduced an alternative cutback scheme for the nonlocal model, that allows to keep the results of most of the ips that immediately converged, and only do cutbacks in regions where some ips are in big trouble. Only works for nonlocal model and state integrator 2.

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)

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

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

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
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

some minor improvement on precision detection: checking only once (in prec and no longer in math and crystallite), added one more 4/8 switch for LAPACK, as there is no single precision FFTW, stopping compilation for spectral method if FLOAT=4
...
new function in IO to print integers without leading zeros, implemented it at some places in the new spectral solver (reporting still needs some serious polishing)
updated preprocessing for documentation to handle precision correctly
2012-08-30 20:26:28 +00:00
0959ff3299
substituted hand written matrix inversion by LAPACK version with precision selection.
...
also introduced check for inversion into DAMASK_spectral_Utilities.f90 for the stress BC calculation. This part is further improved by using 5% of the reference stiffness to avoid trouble in the fully plastic regime (where the stiffness is underestimated)
Test for Marc 2010 is updated because the new inversion give slightly different results near 0 (order of e-13)
