Martin Diehl 5a1e73b53d added set_timelimit functionality to fortran-wrapper of FFTW and introcudec it to DAMASK_spectral.f90 2011-11-21 18:48:38 +00:00
Martin Diehl 566f16b6e9 implemented calculation of divergence in real space, polished spectral debugging 2011-11-21 18:12:40 +00:00
Martin Diehl dc6c29a910 important bugfix for reading in results in case of restart 2011-11-17 22:11:05 +00:00
Martin Diehl 5ef73e164a restructured algorithm: moved into loop to reallocate fields and replan FFTW in case resolution changes during runtime ==> regridding
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.
step counting rectified
added additional output of deformation gradient volume min and max
2011-11-11 14:17:43 +00:00
Martin Diehl de96e99bca corrected determination of restartRead from commandline (now done by FEsolving instead of DAMASK_spectral_interface)
recompiled fftw libraries with --enable-shared to make them work with f2py
added draft for compilation test of spectral solver
2011-11-07 18:25:10 +00:00
Krishna Komerla 49c0b8a3fd restructured restarting capabilities 2011-11-07 11:04:57 +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

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

added some information from Tuning workshop in Aachen regarding tuning/parallelization

added slides with information how to prevent segmentation fauld

2011-09-13 15:54:06 +00:00
Martin Diehl e8628996ff added IO error in case mixed BC that allow rotation are given 2011-09-02 13:50:05 +00:00
Martin Diehl 0469d37fc3 cleaned and restructured output on screen, changed L_inf norm to L_2 for calculation of error in Fourier space.
removed unnecessary function from math.f90
added some documents/manuals regarding spectral method
2011-08-31 14:37:01 +00:00
Martin Diehl 4fb1cb8f87 merged calcmodes, i.e. equilibrium and fulfilling of stress BC is done in one step,
made convergence independent of size and resolution,
polishing output in DAMASK_spectral.f90
added function to compute eigenvalues without eigenvectors and function to convert a 3x3 logical to a 9 vector in math.f90
removed obsolete variable in numerics.f90
2011-08-26 14:06:37 +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
2011-08-10 17:45:37 +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
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...
2011-08-03 17:57:28 +00:00
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
Martin Diehl 3adb7ab382 corrected makefile, now working again without giving standard values explicitly.
did some small modification in order to make it possible to compile with gfortran. Changed NaN=0.0/0.0 to bitwise representation (3 different ways)
2011-08-01 10:11:32 +00:00
Christoph Kords fb121b1435 * boundary condition masking changed
* damper initialized with one 
* inversion of Mandelized stiffness tensor does not work, have to use plain tensor
* new functions in math that allow for conversion between Mandel and Plain tensors
2011-07-29 15:57:39 +00:00
Martin Diehl 72d20875de added some switches and variables to the makefile to make it more flexible
DAMASK_spectral.f90 is a "debug version" with a number of different criteria to determine divergence. will be removed later on.
2011-07-25 16:30:21 +00:00
Martin Diehl 09ba92c26e added and rearranged error messages, polished output and simplified calculation of f depending on fdot or L
guessing along former trajectory is now on per default, 'guessreset' and 'dropguessing' switch it off.
2011-07-14 09:37:31 +00:00
Martin Diehl 56340fd487 changed input of loadcase. Now fdot (time derivative) can be used instead of velocity gradient. Velocity gradient needs to have each line fully or not at all defined, as for other loadcases the stress BCs are not known in advance. Also added the possibility to keep guessing along trajectory of former loadcase.
changed back to use the compliance of initial linear material behavior.
added counter of non-converged steps
renamed compiler flags in makefile
2011-07-13 16:33:12 +00:00
Martin Diehl a08eaecf4e polishing (names of variables, spaces, comments etc.)
renamed mpie to DAMASK in IO.f90 error message
2011-07-07 15:27:35 +00:00
Martin Diehl a561ef1cf5 corrected calculation of divergence in Fourier space, removed normalization of normdyad (was useless), now using correct compliance for calculation of stress BC. 2011-07-07 10:03:55 +00:00
Franz Roters 18a5841bc5 keyword freq for frequency of output writing was not evaluated when reading loadcase file 2011-07-07 09:18:05 +00:00
Onur Guevenc e889b69bec Ability to define loglinear time increments by using 'logincs' or 'logsteps' instead of 'incs' in loadcase file is added. 2011-07-06 13:10:18 +00:00
Philip Eisenlohr 314adae1bb spectral solver can now write result at reduced output frequencies: use 'f', 'freq', or 'frequency' keyword in loadcase definition.
example: ... time 1 incs 100 freq 10 will write output at times 0.0, 0.1, 0.2, ... , i.e., every ten increments only.
2011-06-15 17:48:14 +00:00
Philip Eisenlohr 4a694fa7fd changed wildcard letter from '#' to '*' now consistent with new IO comment parsing.
fixed memory bug with bc_maskvector.

some brushing up here and there...
2011-06-06 15:20:28 +00:00
Christoph Kords ae4c8fa2d8 renaming of "mpieNumThreadsInt" to "DAMAKS_NumThreadsInt" was forgotten here 2011-06-06 08:51:07 +00:00
Christoph Kords 78f74e8991 forgot to use "mesh_ipCenterOfGravity" 2011-05-26 09:23:13 +00:00
Christoph Kords cac45cff96 ip coordinates are now updated every cycle; this is needed for the nonlocal internal stress fields
* Marc: node displacements are added to initial node coordinates (mesh_node0) to get current node positions (mesh_node), then ip coordinates are deduced
* Abaqus: ip coordinates are directly updated, no update of node coordinates!
* Spectral: for the moment no update of either ip or node coordinates! passing only dummy values with initial ip coordinates
2011-05-24 15:57:59 +00:00
Philip Eisenlohr fa98133f8e renamed interface from "mpie_interface" to "DAMASK_interface" 2011-05-11 17:01:03 +00:00
Philip Eisenlohr e5a2d829b0 new substructure with 'include' and 'config' directories
renaming of mpie_... to DAMASK for main usersubroutines

extension of element outputs from 5 to 8 digits (FFT!!!)
