prevented FEsolving from potentially write to a none existing file
started to introduce petsc into the make chain (nothing happens if PETSC_DIR is not set)
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.
lattice.f90, FEsolving.f90: explicitly defined public functions and variables, all others are now private
numerics.f90: changed output format of real numbers, now instead of 0.1eX 1.0e(X-1) is printed to screen
Makefile: now using correct Optimization flags for OPTIMIZATION=AGGRESSIVE
DAMASK_spectral_AL.f90: improved, but still testing. Stress BCs now seem to be handled correctly
removed cut_off parameter for damask_spectral
removed outpot of derived divergence measures and added RMS output in brackets
added comments and options to the makefile
-removed to long lines
-restructured f2py modules and merged make_DAMASK2Python into setup processing
-setup_code.py now sets library path in makefile and asks for compile switches for spectral code
-substituted \ in format strings with $
restructured DAMASK_spectral:
-more logical output and structure of code
-better input for spectral debug parameters
rearranged some logic here and there.
(hopefully) improved readability of debug/standard output.
restarting logic would need some discussion with Martin/Krishna still…
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
you have to specify the job you are restarting from in the job description (cae), if you prepare your input file by hand this is the first line after *Heading
example: if the first job was using Oldjob.inp the first entry in the job description needs to be Oldjob (without the .inp)
as for Marc restart works only from last converged increment, i.e. ther restart writing should be specified like this:
*retsart, write, frequency=1, overlay
Overlay is not essential but saves a lot of disk space and as stated before you can only restart from the last converged increment anyway
0 : only version infos and all from "hypela2"/"umat"
1 : basic outputs from "CPFEM.f90", basic output from initialization routines, debug_info
2 : extensive outputs from "CPFEM.f90", extensive output from initialization routines
3 : basic outputs from "homogenization.f90"
4 : extensive outputs from "homogenization.f90"
5 : basic outputs from "crystallite.f90"
6 : extensive outputs from "crystallite.f90"
7 : basic outputs from the constitutive files
8 : extensive outputs from the constitutive files
If verbosity is equal to zero, all counters in debug are not set during calculation (e.g. debug_StressLoopDistribution or debug_cumDotStateTicks). This might speed up parallel calculation, because all these need critical statements which extremely slow down parallel computation.
Major changes:
CPFEM.f90 =>
1. Moving the initialization out of CPFEM_general into a separate subroutine, which is directly called by the hypela2 (Beware, the Abaqus version must also be modified in order to adapt with this change).
2. Restore primary state variables in CPFEM_init from binary files when requested (Marc flag: restart read).
3. Writing primary state variables into binary files (Marc flag: restart write).
FEsolving.f90 =>
1. Adding functions to recognize Marc restart flags: read and write and the corresponding restart file (parent job).
2. Change the initial value of cycleCounter = -1 in conjuction with the change made the ping-pong scheme
homogenization_RGC.f90 =>
1. Just syntax polishing.
IO.f90 =>
1. Adding functions/subroutines to open binary files for writing the primary state variables for restart purpose.
mpie_cpfem_marc.f90
1. Modification of the general scheme for collection and calculation in order to accommodate the newly added restart feature.
# IO has some additional functionality for Abaqus parsing
# ping pong scheme in FE interface now similar (and more human understandable) in both versions
# mesh has better splitting of different tasks, plus operation on database whenever possible
# FEsolver as new global var to indicate FEM solver type
# computation mode reshuffling: 6 is now Marc special case of recycling...
debugging memory leak closed
debugging counters corrected
center of gravity stored in mesh
state updated is now split into a collecting loop and an execution
updateState and updateTemperature fill sequentially separate logicals and evaluate afterwards to converged
added 3x3 transposition function, norm for 3x1 matrix and 33x3 matrix multiplication in math
non-converged crystallite triggers materialpoint cutback (used to respond elastically)
non-converged materialpoint raises terminal illness which in turn renders whole FE increment useless by means of odd stress/stiffness and thus waits for FE cutback
