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

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
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
2011-08-02 11:17:45 +00:00

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

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

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

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

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

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

removed all math functions only for double precision by the more flexible counterpart, e.g. "dsqrt --> sqrt", "dsin --> sin". Should not cause any harm, as long as "implicit none" is used.
...
Now it is possible to compile a single precision spectral solver/crystal plasticity by replacing mesh.f90 and prec.f90 with mesh_single.f90 and prec_single.f90.
For the spectral method, just call "make precision=single" instead of "make". Use "make clean" evertime you switch precision

96d3682d5e
* new global integer variable "numerics_integrationMode" (1 indicating integration of central solution, 2 indicating integration of perturbed state)
...
* combined "integrator" and "integratorStiffness" in new global variable "numerics_integrator"
2011-02-23 08:29:51 +00:00
d835380bc0
* "constitutive_nonlocal_flux" is set to zero in "constitutive_nonlocal_dotState", not in "constitutive_nonlocal_microstructure"
...
* dislocation flux and internal stress calculation now consistent with new definition of slip system lattice according to paper (polarity of screws inverted)

restructured constitutive_nonlocal_compatibility and incorporated the "surfaceTransmissivity" in the compatibility calculation
2011-02-16 16:38:18 +00:00
24d33bf2ff
* added a new material parameter "surfaceTransmissivity" (default value 1.0) which allows to change the transmissivity of the material surface between 0 and 1
...
* now complaining when encountering an unknown nonlocal parameter in material.config
* use same error ID for all material parameters out of bounds
* symmetric flux calculation in side dotState can now be omitted (because of new treatment of periodicity)
* switching back to "local flux balance" (add leaving and entering fluxes at central MP, don't touch neighbor) instead of "flux distribution" (subtract leaving fluxes from central MP and add them at neighboring MP). This has the advantage that there is almost no need for CRITICAL statements in parallelization, so hopefully this results in some speed up.
2011-02-16 16:35:38 +00:00
8f626c8989
Now able to have real periodicity for fluxes (fluxes leaving the model on one side enter on the other side).
...
To enable this feature one has to add the following somewhere in the marc input file:
$mpie periodic x y z
for having periodicity in all directions
$mpie periodic z x
for having periodicity in x and z direction
etc.
Note that this only works for regular meshes!!!

mpie_spectral.f90: changed fourier transormation, now using the advanced interface to do the tranformation both ways with just one call. now also using the same variable for pk-stress in both domains and the change of deformation gradient in both domains.
...
postprocessing: renamed name of python/f2py modul from "reconstruct" to "postprocessingMath", added some numerical operations to use for postprocessing.
2011-02-09 17:47:28 +00:00

* found memory leak in nonlocal model! "constitutive_nonlocal_rhoDotFlux" has to have upper index bound of 10 for second dimension, not 8.
...
* need to recalculate dislocation velocity in postResults, otherwise we take values of last perturbed state! So the following outputs were up to now showing the perturbed state: shearrate, dislocation velocity, all density rates!

2011-02-07 14:35:42 +00:00
faba13f7fd
* now able to introduce some scatter in the initial single dislocation density (only for nonlocal model!) ; setting the parameter "rhoSglScatter" to a positive value generates a gauss distribution for the dislocation density with standard deviation equal to "rhoSglScatter"
...
* dislocation stress calculation is only done for nonlocal constitution ("/nonlocal/" keyword is present in material.config)

if nonlocal ip has local neighbor assume perfect transparency of the (perhaps virtual) phase boundary. this is only a quick fix! need to rethink the way constitutive and real boundaries are treated!
2011-01-11 18:00:29 +00:00
6a3dd78259
fluxes are disabled when keyword "/nonlocal/" is omitted in the material.config (this is a way to use the constitutive_nonlocal model as a local dislocation based model)

changed makefile: material subroutines are now compiled using openmp, enabled linux threads for fftw3 (also did some slight changes to enable that in the fortran source code)
...
renamed mpie_spectral2.f90 to mpie_spectral2d.f90 (testing file, not properly working at the moment)
changed file extension and variable names in mpie_spectral.f90 and mpie_spectral_interface.f90 from "mesh" to "geom". Removed direct output from mpie_spectral.f90, all output is now base on materialpoint_results(:,1,:)

2010-11-26 11:50:20 +00:00
6b199e7830
allow 2digit values to be read in for MPIE_NUM_THREADS
2010-11-25 10:34:55 +00:00
ea6a6c9503
* environment variable MPIE_NUM_THREADS now determines number of threads used in parallel regions
...
* default value of the OMP_NUM_THREADS variable has to be restored at the end of mpie subroutine, since marc also seems to use and change(!) this
* usage: "export MPIE_NUM_THREADS=<number of threads>" to set variable in shell, then restart mentat and compile with option 3 (at the moment this does only work on ws 6, since all other workstations use compiler option "-save"; this puts all local variables by default in static memory, which is a killer for parallelization!)
2010-11-19 17:45:27 +00:00
b9b226548c
* enclose wall time measurement for LpAndItsTangent and count of leapfrogbreaks by CRITICAL construct
...
* better use SINGLE (having an implicit barrier at the end) instead of MASTER construct
* deleted all explicit BARRIERs after do loops since parallel loop construct implies barrier at the end
2010-11-19 17:29:29 +00:00

4f267f4375
parallelization now works properly (not yet tested extensively though):
...
* had to add some BARRIER constructs
* only the master thread is allowed to increase the state counter
yet parallelization seems not to give a significant decrease in calculation time with nonlocal model (because of too many CRITICAL statements?)
2010-11-11 16:16:05 +00:00
14594dc9e2
* OpenMP does not like unbounded array subscripts in function calls
...
* some write statements were still not enclosed by CRITICAL construct, some needed a MASTER construct
2010-11-11 13:14:53 +00:00
bca951325d
* cpfem will now produce a warning if all components of the stiffness tensor are close to zero

54748bb6a5
cycleCounter reset was 0 now -1 ==> occurence of jacobian calculation is now correct, i.e. always calc at start of new increment
2010-11-04 18:15:50 +00:00
405d5529e7
* checked and corrected parallelization of code. compiles now successfully, but simply aborts computation with first parallel directive without any comment :-(((
...
* also put a call to constitutive_microstructure at the start of each crystallite_integration subroutine like it was before. need that for nonlocal model in case of crystallite cutback
2010-11-03 17:22:48 +00:00

2010-11-03 14:58:11 +00:00
763c20b302
Introducing the capability to restart jobs that crashed in the middle of sims. At the moment, this feature is exclusive for Marc.
...
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.

in RKCK45 state integration: dotState was not saved in last Runge-Kutta step
2010-10-27 08:48:04 +00:00
f5f3ef5ecc
* have to reset dotState to zero before call to collectDotState (only important for nonlocal calculation)
...
* in Fixed Point Iteration: update dependent states after state preguess was missing; on the other hand, the first call to constitutive_microstructure was obsolete
2010-10-26 14:04:33 +00:00
4439282239
no change to previous version, just forget to mention one important change of the last revision:
...
* fluxes are now again calculated and distributed only! by the originating material point. this means that the central MP might change the dotState of its neighbor. have to see whether locks slow down parallel computation
2010-10-26 13:49:58 +00:00
62d06001ea
* corrected compatibility for screws (always positive)
...
* detection of grain boundary in constitutive_nonlocal_microstructure with the help of transmissivity
* enforce positive densities in constitutive_nonlocal_microstructure (needed because dotState does not create cutbacks for negative densities anymore)
* reset single mobile densities below certain threshold to zero (also done in constitutive_nonlocal_microstructure)
* constitutive_nonlocal_kinetics only gets local state variable as input, no need for the entire array here
* dv_dtau is always positive
* multiplication is only active when there is already some initial density of the respective type
2010-10-26 13:42:18 +00:00
366d52bd71
* former "relevantRho" and "relevantResistance" is renamed to "atol_rho" and "atol_resistance" and now used as an absolute tolerance for the state residuum. before it was used rather as significant state, so whenever the state dropped below that value it was considered converged. (In dislotwin and titanmod constitutive law there is only one value atol_rho which is used for all the states, though the state array consists not only of densities. We need further parameters here!)
...
* somewhat simplified convergence check for adaptive euler and runge-kutta
2010-10-26 13:16:37 +00:00
26cb618b6d

3837dad51e
fixed bug in mpie_spectral.f90 concerning spectral method (now deltaF hat get the right value)
...
added mpie_spectral2.f90, a version that should get the new algorithm proposed in 2010. until now, it is the same as mpie_spectral.f90 (large strain formulation by suquet et al) but with c2c, c2c FFT
2010-10-20 08:59:00 +00:00
e49de75fe3
stiffness calculation now only needs a single function call to the respective integrator method instead of one call per grain (which seems to heavily slow down the computation). also no special treatment for non-local material points anymore.
2010-10-15 14:57:13 +00:00

2010-10-13 16:04:44 +00:00
724960686f
* in nonlocal model: dislocation flux now with valid description also for large angle grain boundaries; transfer of dislocations from one slip system to the other according to new variable "constitutive_nonlocal_compatibility" which depends on the angle between slip plane normals and slip directions and is updated once per cycle in function "crystallite_orientations"
...
* reactivated debugging functionality for "non-standard" integration methods
2010-10-12 13:08:54 +00:00
efd92d9b51
allocation of special state variables for "non-standard integration" was erroneous. used to produce segmentation fault for integration method 4 and 5.
2010-10-12 12:11:24 +00:00
fce7590c17
* now able to choose method for state integration (integrator and integratorStiffness in numerics.config); standard is "Fixed Point Iteration", which is basically the same as before; others available are "Explicit Euler", "AdaptiveEuler", "Classical Runge-Kutta" and "Runge-Kutta Cash-Karp"
...
* now remembering stiffness similar to how we do it for Lp etc.; avoids undefined stiffness values for nonconverged stiffness calculation
* non-local stuff:
* changed non-local kinetics (Gilman2002)
* enforce zero shearrate for overall carrrier density below relevant density
* enforce zero density for those states that become negative and were below relevant density before
* dislocation velocity is not limited by V^(1/3) / dt anymore
2010-10-01 12:18:49 +00:00
9927cd7adb
changed format of resolution. instead of reading exponent of two, now the number given equals directly to the number of FPs. Allows us to use arbitrary number of FPs.

first call to hypela2 in inc 0 is done with computation mode 2 (=plain calc), but since rev. 539 the second call was done with computation mode 6 (=only return values) instead of 2. This doesnt work, because computation mode 2 might calculate stress and tangent for all materialpoints, but the mapping from lattice to current configuration is only done for the element/IP that triggers the call.
...
So switched back to the former order of calls which also works for marc2010:
el 1 IP 1 | el 1 IP 2
|
inc mode lovl | inc mode lovl
------------------ | ------------------
0 2 6 | 0 2 6
1 6 4 | 1 6 4
1 4 6 | 1 3 6
1 6 4 | 1 6 4
1 1 6 | 1 2 6
Still to be checked:
according to Franz the lovl order could be different in contact analysis (e.g. starting with lovl 4 instead of 6)

beware that crystallite output "orientation" now by default returns the orientation as quaternion. if you want euler angles instead, you have to add "eulerangles" as a crystallite output in your material.config file (see material.config template).
for input of orientations in the texture block of the material.config you still have to specify the rotation in terms of euler angles, quaternions are not yet supported for input.
