Martin Diehl d83150be1b now capturing "terminallyIll" for basic solution, should end in a automatic cutback of time steps for the spectral solver 2012-08-29 05:50:42 +00:00
Martin Diehl 3106b8ce0c corrected definition of integer type for gfortran 2012-08-29 05:19:35 +00:00
Martin Diehl d089c12947 abaqus seems to have similar problems with the openmp lib as marc (use module vs. include file), i hope this fixes the crashes 2012-08-28 19:48:38 +00:00
Martin Diehl 5e9e8497e6 new solver is now compiling without a PETSc installation, however only the plain basic solver is available then.
also removed reporting of PETSc related variables in the case it is not installed/found
2012-08-28 19:19:47 +00:00
Martin Diehl 0f64289d75 fixed bug causing trouble with ifort 11 (abaqus) 2012-08-28 19:10:54 +00:00
Martin Diehl 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
Martin Diehl 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

Christoph Kords 9214da4465 added missing labels to list of available outputs 2012-08-27 12:41:57 +00:00
Martin Diehl 96ba5ecae4 moved some more 'mesh related' functions for post processing from math.f90 to mesh.f90
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

Christoph Kords 3cd5fa90e8 corrected dislocation multiplication term for special case of zero density 2012-08-24 11:36:46 +00:00
Christoph Kords 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
Christoph Kords 222aed9f60 derivative of velocity with respect to resolved stress was flawed; now much better convergence of stress integration for nonlocal constitutive law 2012-08-21 14:40:01 +00:00
Christoph Kords ad7381cfdd maximum relative step length in stress integration cannot decrease below 1

Christoph Kords b2aacf9ca4 rates in constitutive_results are taken directly from last converged step and not calculated again; added output of rates for annihilation of screws and deposition of edge jogs on collinear system 2012-08-16 11:03:22 +00:00

Pratheek Shanthraj c2c31a0a59 added SolverBasicPETSC module to the new FFT solver (solves the basic scheme using PETSc when mysolver = basicpetsc in numerics.config)
some bug fixes
2012-08-14 16:58:23 +00:00
Christoph Kords 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
Christoph Kords 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
Christoph Kords eae9a34c6b corrected debugging output: extreme values of returned stress and jacobian belong to cpfem debugging, not homogenization 2012-08-14 11:48:43 +00:00

Philip Eisenlohr b4103b205d parts of the material.config can now be set to echo their content back into the log-file (i.e. STDOUT / unit 6)
use keyword "/echo/" before first section in the respective parts that you want to see echoed back into the log file.
2012-06-26 10:24:54 +00:00

Franz Roters 380f40561b first calculation of Tstar still used hard coded Hooke, now usese constitutive_TandItsTangent(...) 2012-06-18 07:26:34 +00:00
Martin Diehl b2fd3e1180 introduced preprocessor identifiers Marc, Abaqus, and Spectral to enable conditional compilation. This allows deleted dummy functions that are used by one solver only.
Mainly affected modules are IO and mesh. Most of the changes in mesh result from reordering the functions when grouping them depending on their solver.
Further advantage is that FE solver do not need FFTW and kdtree2 anymore. The include files for these two libraries moved to DAMASKROO/lib now as I figured out how to use a include path in the Makefile.
Put all the files I got when testing compilation with abaqus in a folder which to become the abaqus compilation test.
2012-06-15 16:10:21 +00:00
Martin Diehl eb39d332bd ULTRA OPTIMIZATION wasnt working anymore, seems to be related to Bertholds update of ws12 and ws13. had to remove -static from optimization string to be able to link again. Added some support for IKLM, but this didn't solve the problem 2012-06-13 17:19:16 +00:00
Martin Diehl 3ef17c208b set default lapack to lapack instead of acml, added definition of makro for spectral solver for later use in preprocessor 2012-06-13 13:45:58 +00:00

Franz Roters a5c27f22ca now uses unit 5 for file name inquiery (unit 6 points to stdout in 2012, might be a bug though) 2012-06-13 07:28:43 +00:00
Franz Roters 5b7f2e122e fixed usage of OpenMP function library 2012-06-12 09:44:05 +00:00
Christoph Kords fc7b4d6471 new function stateJump, which takes care of immediate changes in the state (deltaState); this introduces discontinuities in the state evolution; therefore this is always and only once done after each integration step, so no evaluation of deltaState for intermediate steps of e.g. the Runge-Kutta integrator; otherwise integration becomes a pain without significant gain in accuracy
deltaState now successfully tested for nonlocal model; was not correct for integrators 1,4,5 before
2012-06-06 15:11:30 +00:00
Martin Diehl fa7f9866df removed phase contrast/preconditioning
added information on itmin in output, impoved output
