fixed bug that 'ULTRA' was not using -O3 for most of the compiling...
2011-12-16 09:11:03 +00:00
Philip Eisenlohr a8dece8694 adopted use of general damask package ("import damask" instead of "damask_tools") 2011-12-15 08:52:41 +00:00
Christoph Kords b2547e0117 Math inversion used to return zero (math_inv3x3) or error (math_invert3x3) for negative determinant. Now checking whether the absolute(!) value of the determinant is close to zero to avoid singularities, negative determinants are very well allowed. 2011-12-14 08:55:24 +00:00
Martin Diehl 031a00237f improved makefile, no directly linking to files of acml

2011-12-06 17:46:33 +00:00
Martin Diehl 5ebeb96e85 made DAMASK to work with gfortran:
-removed to long lines
-restructured f2py modules and merged make_DAMASK2Python into setup processing

-better input for spectral debug parameters
2011-12-06 16:58:17 +00:00
Philip Eisenlohr efadf9f728 mainly fixed error in output of spectral results (1:N,…) instead of (N,…)
rearranged some logic here and there.

(hopefully) improved readability of debug/standard output.

restarting logic would need some discussion with Martin/Krishna still…
2011-12-04 10:01:32 +00:00

  (grain count
   sub-block[s] of crystallite and constitutive)
2011-11-23 09:09:00 +00:00

introduced parameters for selective debugging of spectral code and partly introduced the advanced divergence calculation again which is controlled by debug.config
added switch in numerics to control divergence behavior (uncorrected and corrected by phenomenological factor)
added precision directive to all values I found
2011-11-15 17:54:18 +00:00
Krishna Komerla 60c9293baf restarting seems to work, spectral solver writes own defgrad to disk.

2011-11-11 14:17:43 +00:00
Christoph Kords 860594d9a4 forgot to multiply shearrate with timestep in order to get accumulated shear 2011-11-09 10:26:00 +00:00
Christoph Kords 6dc8a4d530 check for LFC only if there is any slip activity at all; also increased safety factor from 1.2 to 1.5 2011-11-09 09:55:39 +00:00
Christoph Kords 7033e84fc7 new outputs "accumulatedshear", "velocity_edge", and "velocity_screw" (the latter two replace the output "dislocationvelocity") 2011-11-09 09:22:52 +00:00

2011-11-07 18:25:10 +00:00
Christoph Kords 8bc39fcd48 immobile density output keeps its sign 2011-11-07 15:46:40 +00:00
Christoph Kords 34adec74e8 corrected wrong indices into state array for velocity 2011-11-07 15:17:58 +00:00
Krishna Komerla 49c0b8a3fd restructured restarting capabilities 2011-11-07 11:04:57 +00:00
Christoph Kords 7dfb96a3da constitutive_nonlocal:
dislocation velocities are stored in the state, so we actually now have three "parts" of the state, the basic states that are updated by "constitutive_dotState" come first, then the dependent states that are calculated by "constitutive_microstructure" follow, and finally we have a last part reserved for other variables that just use the memory reserved by the state array and are updated somewhere else.

constitutive:

LpAndItsTangent does not need the full state, but only the local state, so changed that at least for the nonlocal constitutive law
2011-11-04 13:12:17 +00:00
Christoph Kords 9d1bc584d0 corrected stress integration scheme: now use norm(Lpresiduum) as a target function for Armijo's rule instead of whole tensor Lp; also corrected the guess for the improvement in Lp 2011-11-04 12:57:12 +00:00
Christoph Kords ca3d21a3b6 Depending on which state integrator one uses for the stiffness calculation, the initial state has to be chosen accordingly: e.g. for FPI choose last converged state, but for explicit RK choose converged state from start of increment (in case of explicit euler no state integration at all, but only stress integration). For this purpose we also need to remember "Fe" which now follows the cutbacking procedure as it is used for "Fp". 2011-11-04 12:44:50 +00:00
Martin Diehl ee7022d8cf correctet random seed generation to work with gfortran. 2011-11-04 10:29:35 +00:00
Martin Diehl c2eac36b48 started to implement restart facilities for spectral solver.
restart write is on per default
restart read is switched on by using --restart or -r INT where INT gives step at which the calculation should restart
setting INT to a value <1 will turn restart write off
2011-11-03 19:32:11 +00:00

2011-11-02 14:38:42 +00:00
Claudio Zambaldi 447e69019c Introduced environment variable DAMASK_ROOT.
It is set in the DAMASK root folder by running damask_env.sh
Much needed in the testing routines so far (try ./testing/run_tests.py)
damask_env.sh could also trigger other scripts to get to a working setup after fresh checkout. For example it could run 
./processing/setup/setup_processing.py
./code/setup/setup_code.py
if it finds that we have a fresh checkout.
2011-10-27 17:55:42 +00:00

2011-10-18 09:16:18 +00:00
Martin Diehl 4989535500 new version 3.3 of FFTW. Compiled with gfortran but only for multicore support (single core library is still the old version 3.2.2). Now either POSIX threads or OMP can be used by choosing the corresponding library file
Some further polishing (besides of new description for FFTW) of the makefile
2011-10-13 12:41:01 +00:00

did a lot of polishing:
- removed unnecessary "return" before end of subroutine or function:
- changed undetermined array length (:) to (1:3)

To prevent problems with some code analysing tools:
- "3D oneliner loops" (with ";) only for "do" and "enddo" at the same time
- removed line continuation in OMP statements

made the makefile more flexible, removed heap-arrays switch

Christoph Kords b300cc7faa ip volume is now based on the determinant of F. "mesh_ipVolume" represents the initial volume and is multiplied with det(F) wherever the current volume is needed. Since this works for all solver types, the "volume" output in crystallite is now also correct for spectral method and abaqus. 2011-08-19 11:18:56 +00:00
Martin Diehl f99bf63397 removed functions added for debugging of divergence calculation to math.f90
corrected calculation of stress BC condition. Depending on given BC, the stiffness matrix is reduced and than inversed. Then it is filled with zeros and used for the calculation of the correct change of deformation gradient. All calculation is done using dP/dF

Christoph Kords 1ffb59a96a Calculation of current ip volumes now working. Crystallite output also reflects current grain volume, not reference volume. However, this is only available for Marc. Abaqus and spectral method still return the reference ip volume. The ip coordinates though are correctly updated for all solver types. 2011-08-10 16:37:17 +00:00
Martin Diehl 34de2e301b DEBUGGING VERSION for calculation of Divergence (various methods implemented). DO NOT USE. Wait for next update coming in a few minutes 2011-08-10 16:02:13 +00:00
Martin Diehl bb1ca2330b added option to enable use of AMD math core library, added comments on the various parameters 2011-08-10 16:00:02 +00:00
Onur Guevenc 31b60b8814 changed debug intensity so that the artificially high stress and stiffness values in collection cycles do not get printed out anymore... 2011-08-03 17:59:31 +00:00
Onur Guevenc 4f1cb3a8af exchanged forall with nested do loops... Bye, bye smatrix warning, will miss you!! 2011-08-03 17:58:16 +00:00
Onur Guevenc 907965272b added option to build DAMASK_spectral without openMP (make OPENMP=OFF)
fixed bug in bc_temperature assignment that was hitting memory.
Temperature is taken from the first loadcase and evolves from there in an adiabatic fashion for the moment. I.e. T-specifications from later loadcases are ignored...

Martin Diehl b5abd6f203 adding new option OPTIMIZATION with values OFF, DEFENSIVE and AGGRESSIVE to makefile. Polishing of makefile and DAMASK_spectral.f90 2011-08-03 07:54:32 +00:00
Onur Guevenc 64435b8a97 loadcase takes 'temperature' (or 'temp') as input. Previously it was hard-wired. 2011-08-02 13:58:28 +00:00
Christoph Kords 422d6d9c6c slight correction of debugging output 2011-08-02 12:36:08 +00:00
Christoph Kords ef7405fe21 Stress integration now uses Armijo rule to find an appropriate correction of Lp: decreases step in case that residuum does not improve significantly, accelerates as usual in case of good convergence. This turned out to improve convergence behavior. 2011-08-02 11:29:08 +00:00
Christoph Kords 6f859e99de * internal stress calculation now considers dead dislocations always at the interface, not at the center of the IP volume; used to merge them together with "normal" dislocations for stress calculation.
* dislocation flux is blocked if we encounter a sign change in the resolved shear stress from the central ip to the neighbor
* do not set density to zero if below certain threshold; this creates an artificial sink term

Christoph Kords 0373fa64e4 have to initialize constitutive_state during constitutive_init, since the first call to constitutive_microstructure (where we already need the state) is done before the cutback scheme starts. 2011-08-02 11:10:41 +00:00
Martin Diehl 75c67f53f7 introduced alternative location for material configuration.
If present, the >>>JOB.materialConfig<<< file takes precedence over the standard >>>material.config<<<
