...
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.

documented utilities and structured, worked on the restart capabilities of the new basic solver
2012-10-24 11:31:40 +00:00
5ad0eda1b6
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
b9f97ba5da
unified naming scheme, fixed a bug in the new basic scheme, and added a statistic file similar to abaqus to store the information on needed cut backs and iterations for each inc

fixed bug with thermal annihilation producing negative density in case of very small dipole density and high climb velocity
2012-10-04 18:08:40 +00:00

...
PLEASE RUN setup_code.py IF YOU DO MARC SIMULATIONS, THE INTERFACE HAS CHANGED
2012-10-02 12:46:58 +00:00

new scaling feature in numerics (unitlength) did not scale the reference coordinates in the first place; now this is taken care of in mesh.f90, so scaling should work properly
2012-09-25 16:21:58 +00:00
d0fd3c03c5
forgot to check in; belongs to rev 1762
2012-09-24 16:22:25 +00:00

2012-09-24 12:10:28 +00:00
8336d0705c
new numerics parameter "unitlength" that scales the model size in DAMASK; this enables to use very small models in marc without getting any numerical problems for example with contact which does not seem to work when using very small numbers

dislocation density below a single dislocation per IP considered not significant
2012-09-04 16:56:37 +00:00
22812c9a91
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
299d9e6bc4
fixed bug in seed initialization that didn't allow to redo calculations that started with a random seed. Now the whole random seed array is set to one value, previously only the first one was reported and the remaining ones were random
...
removed old random function used by halton
2012-08-30 14:58:30 +00:00
d80b45c1d9
added relativistic correction of velocity (maximum velocity given by parameter in material.config); probability of thermal activation in velocity law not allowed to be greater than one.
...
output of creation rate for edge jogs now for own system, not collinear.
check for negative densities in dotState now uses absoluteToleranceRho instead of significantRho.
2012-08-30 07:33:13 +00:00
8e3b547cbd
changed numerics.f90 back to the old openmp statement as this doesn't seem to cause the problem and is standard conforming
...
corrected typo in constitutive_j2.f90 that might cause abaqus to crash
now running 20 tests of abaqus in order to have a decent statistic about the crash behavior
improved abaqus_v6.env
2012-08-29 16:16:10 +00:00
84e3f94424
added flush for easier debugging
2012-08-29 15:23:43 +00:00
d83150be1b

5e9e8497e6
new solver is now compiling without a PETSc installation, however only the plain basic solver is available then.

0f64289d75
fixed bug causing trouble with ifort 11 (abaqus)
2012-08-28 19:10:54 +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)
2012-08-28 16:59:45 +00:00
73349d02f5
merged precision info into the file prec.f90 and removed prec_single.f90
...
precision information is now parsed as a makro, defined by the compiler, eg. -DFLOAT=8 for 8 byte long floats or -- in case no values is given -- for the FEM wrapper by the interface files.
Please don't forget to run setup_code.py !!!!!!!!!!!
abaqus_v6.env is adjusted to specify the standard precision (float=8, int=4) and got some extra compilation options, some deprecated warning supressors are removed
Optional Marc modification will follow that allow automatic selection of suitable precision

...
f2py functions remaining in math.f90 now uses assumed size arrays in order to have simpler interfaces. This is only working with python 2.7!
changed python pre- and postprocessing scripts.
If you encounter any problems whith core modules, try to remove the old core.so in the lib/damask

2012-08-24 11:36:46 +00:00
4f67d04c69
new parameter "significantRho" for nonlocal constitutive law ; density below this value will hardly contribute to dislocation glide or any dislocation reaction ; old parameter "absoluteToleranceRho" is now used only for its initial purpose, namely the absolute tolerance in the state integration
2012-08-23 05:48:21 +00:00
222aed9f60
derivative of velocity with respect to resolved stress was flawed; now much better convergence of stress integration for nonlocal constitutive law

...
some bug fixes
2012-08-14 16:58:23 +00:00
f5e7d576f1
introduced annihilation of screw dipoles; so far no thermal activation, but immediate annihilation; each annihilated screw dipole leaves behind an edge jog of same length as the dipole height on the collinear system
2012-08-14 12:26:20 +00:00
c1c5941733
stressAndItsTangent:
...
when winding forward to last substep in increment, also do the calculation if this substep is below "subStepMinCryst";
output of "wind forward" and "cutback" info only for crystallites that are still "todo"
integrateStress:
maximum component in Lp determines absolute convergence criterium:
aTol = max(maxLpComp * rTol_fromConfig , aTol_fromConfig)
this ensures that small values in Lp do not spoil the convergence, similar to the effect of the relevantStrain parameter before (not needed anymore in the stress integration)
2012-08-14 12:07:59 +00:00
eae9a34c6b
corrected debugging output: extreme values of returned stress and jacobian belong to cpfem debugging, not homogenization
