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
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
64435b8a97
loadcase takes 'temperature' (or 'temp') as input. Previously it was hard-wired.
2011-08-02 13:58:28 +00:00
422d6d9c6c
slight correction of debugging output

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.

* 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
2011-08-02 11:17:45 +00:00
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
75c67f53f7
introduced alternative location for material configuration.

If present, the >>>JOB.materialConfig<<< file takes precedence over the standard >>>material.config<<<

2011-08-01 10:11:32 +00:00
06a4ac2565
fixed bug (segmentation fault) occurring for non-renumbered meshes: ipNeighborhood building did use FE IDs of twin nodes to address memory -- dangerous..!

fb121b1435
* boundary condition masking changed
...
* damper initialized with one
* inversion of Mandelized stiffness tensor does not work, have to use plain tensor

2011-07-29 15:57:39 +00:00
aa714a3d84
some textconstants were wider than specified in the format string, this might have caused Abaqus to crash due to an illegal memory reference (signal 11)
2011-07-29 14:54:26 +00:00
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

somehow forgot to move the numerics.config into the config subdir...
2011-07-21 08:40:45 +00:00
e92e5cae53
restarting now works with Abaqus (standard, cannot test explicit due to lack of license)
...
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
2011-07-18 09:15:20 +00:00

small output polishing
2011-07-15 12:25:38 +00:00
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
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

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
18a5841bc5
keyword freq for frequency of output writing was not evaluated when reading loadcase file
2011-07-07 09:18:05 +00:00
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
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

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

Internal stress calculation in nonlocal model: instead of integration of excess gradients (->Bayley) we now sum up contributions from adjacent superdislocations within a certain radius R. When periodicity is used, also periodic images are considered in stress evaluation.
2011-03-29 07:34:33 +00:00
3d51dd36fa
* Introduced preprocessor directives in order to suppress compilation of most write statements when using openmp. This tremendously improves efficiency of parallelization.
...
* Also added some more openmp directives to increase percentage of parallelized code.
* "implicit none" was missing in two subroutines of homogenization and constitutive.

No need to call constitutive_microstructure at the beginning of each crystallite step, since it's already been done at the end of the previous step. Just do it once after initialization to start with correct values for the dependent state variables.
2011-03-21 10:35:42 +00:00
11138e3ee2
debugging output is now controlled by the "verbosity" parameter in the debug.config ranging from 0 (=almost no output) to 8 (=very detailed output)
...
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.
2011-03-21 10:31:17 +00:00
9d7ede7e03
extreme values of stress and jacobian now recorded in CPFEM_general. variable declaration and generation of output moved to debug module.

235266b169
openmp parallelization working again (at least for j2 and nonlocal constitutive model).
...
In order to keep it like that, please follow these simple rules:
DON'T use implicit array subscripts:
example: real, dimension(3,3) :: A,B
A(:,2) = B(:,1) <--- DON'T USE
A(1:3,2) = B(1:3,1) <--- BETTER USE
In many cases the use of explicit array subscripts is inevitable for parallelization. Additionally, it is an easy means to prevent memory leaks.
Enclose all write statements with the following:
!$OMP CRITICAL (write2out)
<your write statement>
!$OMP END CRITICAL (write2out)
Whenever you change something in the code and are not sure if it affects parallelization and leads to nonconforming behavior, please ask me and/or Franz to check this.
2011-03-17 10:46:17 +00:00
