2013-09-18 14:07:55 +00:00

- Error message when the c/a ratio for hcp is higher than 2 (no physical sense).

Martin Diehl cb16b30409 set output order of spectral parameters to more reasonable one 2013-09-17 09:19:16 +00:00
Martin Diehl 3bf0ed84c8 some comments and minor improvements.
removed tol_gravityNodePos from prec because it's not used
tol_math_check is now used by spectral driver to check rotation
2013-09-14 10:59:35 +00:00
Christoph Kords 5f973a21c0 require all hardening coefficients/ non schmid coefficients to be specified in material.config, do not silently ignore any
warning message now more meaningful (?) when using less than maximum number of slip families
2013-09-12 14:47:09 +00:00
Martin Diehl ddfc40afe6 improve restart test, deletion of results was messed up. fixed restart for BasicPETSc, AL and Polarization currently don't run when restarting 2013-09-05 12:07:58 +00:00
Christoph Kords 4ebf46d2ac nonSchmidProjection was reset to zero each time during instance loop in init, so entries from previous instances got lost; fixed that 2013-08-23 13:53:03 +00:00
Christoph Kords 1f77594ca0 dislocation velocity was not correctly stored to state in last version 2013-08-21 13:54:36 +00:00
Christoph Kords 4f8664baa3 in kinetics: non schmid stresses only influence peierls mechanism, but not solid solution hardening; as a result the derivative of the velocity with respect to the resolved stress has to be split into a Schmid and a non-Schmid part 2013-08-21 12:21:52 +00:00
Christoph Kords ec377a6e8e removed obsolete "dead zone" scaling 2013-08-21 08:39:43 +00:00
Christoph Kords f706ba3ff9 rearranged arguments of "constitutive_nonlocal_kinetics", got "tauTreshold" as argument, not complete state
don't call "constitutive_nonlocal_kinetics" twice for edges in case of nonSchmid behavior, but just call once and copy results from positive to negative edges
2013-08-21 07:55:34 +00:00
Christoph Kords 277972edbd "dv_dtau" argument in "constitutive_nonlocal_kinetics" not optional anymore
renamed "screwStressProjection" to "nonSchmidProjection"
2013-08-21 07:23:02 +00:00
Christoph Kords 39c05e0d9e for bcc: exchanged 2nd and third hardening coefficient to be consistent with fcc; now 2nd is coplanar and 3rd is collinear; added newer reference concerning the bcc hardening coefficients 2013-08-14 11:47:03 +00:00
Christoph Kords e909b825cc correction of hardening coefficients also enabled for bcc
for fcc: now applied to all hardening coefficients, not only hirth, lomer, and glissile
2013-08-14 11:44:30 +00:00
Martin Diehl b8d5f3124f added citation on phenopowerlaw aluminum parameters 2013-08-09 21:24:42 +00:00
Pratheek Shanthraj e62b760a6e added F_avg = F_aim in boundary condition convergence check 2013-08-09 16:25:13 +00:00
Martin Diehl 822fa3d97c forgotten line continuation 2013-08-09 04:16:16 +00:00
Martin Diehl c93373a4ac removed long lines 2013-08-08 19:33:21 +00:00
Martin Diehl 3bb5a5e7b5 line too long in DAMASK_spectral_solverPolarisation.f90, reordered curl calculation for clearer look, fixed test for Marc 2013 2013-08-08 18:10:58 +00:00
Franz Roters 591a3023e8 made plain mode work with Abaqus
ATTENTION plain mode (Marc and Avaqus) does not support writung out the deformed geometries
2013-08-08 15:00:22 +00:00
Christoph Kords 3fcc00910c fixed bug that occured under marc (and abaqus?) with openmp:
"lastLovl" (for marc) and "lastStep" (for abaqus) have to be global module variables in FEsolving.f90 instead of local variables in the respective DAMASK_* files; otherwise they are initialized with zero each time hypela2/umat is called.
2013-08-08 12:53:03 +00:00
Martin Diehl 7f3c24e1f1 fixed some buggy last minute changes in the last commit 2013-08-08 09:13:29 +00:00
Pratheek Shanthraj 23e8fcbc51 updated config file with new convergence parameters 2013-08-08 09:12:12 +00:00
Martin Diehl ac92b90e0b fixed al and pol solver, now checking for div(p) = curl(f) = 0 2013-08-07 17:20:05 +00:00
Christoph Kords f2d6703148 multiplication now sensitive of crystal structure, yet multiplication in bcc identical to fcc except for the contribution of edges which is completely dropped for bcc 2013-08-05 09:26:37 +00:00
Christoph Kords 813ed130b0 nonSchmid behavior now ready to use for bcc with phenopowerlaw and nonlocal constitutive model.
nonSchmid tensors according to Koester,Ma,Hartmaier,2012.
extended lattice_Sslip with non-Schmid tensors (the full non-symmetric tensors are required for the tangent and cannot be retrieved from the symmetrized Mandel notation)
2013-08-05 09:23:21 +00:00
Christoph Kords 9f0fe873ba plain mode (no ping pong) now seems to work for marc, further testing needed
regular sequence of computation modes is
inc 0: 1,1,1,…
inc 1: 0,0,0,…
          7,1,1,…
          0,0,0,…
          1,1,1,…
and so on

after a cutback the computation modes follow as
inc 5: 8,0,0,…
          1,1,1,…
          0,0,0,…
          1,1,1,…

Christoph Kords fa3be9a967 corrected lastLovl introduced in rev2593 2013-08-02 15:44:28 +00:00
Martin Diehl 5b80ef3a4c fixed wrong error calculation in Polarisation and AL solvers, and strictened tolerances for tests 2013-08-02 13:55:44 +00:00
Christoph Kords 8d6b840802 removed variable lastMode from FE_solving, used to be used for detection of first call after ping pong; now this is done by checking for a change in the lovl (macro) or a change in the calculation step (abaqus) 2013-08-02 13:28:50 +00:00
Martin Diehl 74791a6686 corrected invalid error for mismatch_p 2013-08-02 11:48:24 +00:00
Christoph Kords 3d687be8b0 Changed order of blocks associated with different tasks:
backup jacobian
restore jacobian
age results
collect 
calc
This becomes important if multiple tasks are requested by one call to CPFEM_general. In plain mode this could, e.g., be 
1) backup jaco, 2) age results, 3) calc
2013-08-02 11:36:51 +00:00
Christoph Kords 7d2206356e parallelExecution flag now passed as input variable by CPFEM_general; flag is set on the solver level (DAMASK_abaqus_exp.f, DAMASK_marc.f90, etc.) 2013-08-02 11:20:11 +00:00
Franz Roters 4f9dbfa193 last commit also solves problem with infinite loop in case of a cutback in homogenization

2013-08-02 07:59:55 +00:00
Franz Roters a08d263865 remnoved some unused fuctions from use statements 2013-08-02 06:18:41 +00:00
Christoph Kords a7f0f4ed79 moved some small part of the code that remembers maximum and minimum stress/stiffness values to different location 2013-08-01 16:27:37 +00:00
Christoph Kords 728facd451 corrected indentation level of parts of the code
moved debugging output of stress and stiffness to different position in code
2013-08-01 16:10:56 +00:00
Martin Diehl ac2ca43cfc added svn properties 2013-08-01 09:13:46 +00:00
Martin Diehl 2dc985f558 set tolerances to useful values and renamed them.
allowed "keyword = value" in numerics.config (simply removing "=" from line)
2013-07-31 15:03:38 +00:00
Martin Diehl b5a11f9d31 fixed bug in AL, weakened correction slightly 2013-07-30 21:04:41 +00:00
