Christoph Kords d62eddc0cd corrected kinetics law and changed parameters. For solid solution hardening there are 3 parameters: the activation energy, the concentration of obstacles that determines the activation length and meanfreepath, and the obstacle size that determines the activation volume. For the Peierls mechanism there is: the width of doublekinks that determines the activation volume and the Peierls stress for edge and screw.
Still testing needed to check whether the current formulation makes sense or not.

Christoph Kords bbf4f25898 renamed subroutine "mesh_marc_get_mpieOptions" to "mesh_get_damaskOptions" which is now also used for abaqus and spectral input files. The only available option so far is "periodic", which allows for periodic fluxes in the specified direction. Examples for usage (add the following lines to the respective input file, in case of spectral file this goes into the header):
- periodicity in x and z direction for marc:
   $damask periodic x z  
- periodicity in y direction for abaqus:
   **damask periodic y
- periodicity in x and y direction for spectral:
   periodic y x

Martin Diehl c5128e94eb some f2008 standard related correction i didn't check in last time 2012-02-01 20:20:05 +00:00
Martin Diehl 800e291240 made code standard conform to Fortran 2008 (ignoring warning concerning comments beyond character 132). Basically, changing "x" format specifier to "Nx" ("1x") plus removing $ format specifier
added compiler switches for gfortran and ifort to check for standard conformity
old gnu compilers <4.4 are not longer supported because they don't provide the c binding for fftw

Christoph Kords 1330576a01 added new math function "math_deviatoric33" which returns the deviatoric part of a 3x3 tensor
renamed some math functions, so that we have a universal naming scheme: for matrix multiplications use an "x" (e.g. math_mul33x3); don't use the "x" to describe the shape of the tensor that the function is applied to (e.g. math_invert33 instead of math_invert3x3)

Christoph Kords 5a658d1b82 dislocation velocity output for each dislocation type (edge+,edge-,screw+,screw-)
for fcc constitutive_nonlocal_kinetics is called only once and the result is used for each dislocation type, for all other lattice structures we have one call for each dislocation type
2012-01-26 07:43:36 +00:00
Christoph Kords e5407894b5 Reworked kinetics. Now there is a universal law which can be used for both fcc and bcc (and probably even hcp). It mainly consists of an athermal forest cutting part , solid solution and peierls as thermally activated processes, and viscous glide. Therefore, lots of new parameters in the material.config. Not sure yet if the values make sense though.
Also renamed some of the old parameters. 

Unknown constitutive output raises error.

Christoph Kords 8739b9522e dislocation stress does not add to stress field anymore, but is only available as constitutive output for purposes of postprocessing. instead, we now use a backstress term (which is added to the resolved shear stress) that depends on the gradient of excess density on the same slip system. 2012-01-17 10:26:57 +00:00

2011-12-16 09:11:03 +00:00
Philip Eisenlohr a8dece8694 adopted use of general damask package ("import damask" instead of "damask_tools") 2011-12-15 08:52:41 +00:00
Christoph Kords b2547e0117 Math inversion used to return zero (math_inv3x3) or error (math_invert3x3) for negative determinant. Now checking whether the absolute(!) value of the determinant is close to zero to avoid singularities, negative determinants are very well allowed. 2011-12-14 08:55:24 +00:00

2011-12-06 16:58:17 +00:00
Philip Eisenlohr efadf9f728 mainly fixed error in output of spectral results (1:N,…) instead of (N,…)
rearranged some logic here and there.

(hopefully) improved readability of debug/standard output.

restarting logic would need some discussion with Martin/Krishna still…
2011-12-04 10:01:32 +00:00

   sub-block[s] of crystallite and constitutive)
2011-11-23 09:09:00 +00:00

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 49c0b8a3fd restructured restarting capabilities 2011-11-07 11:04:57 +00:00
Christoph Kords 7dfb96a3da constitutive_nonlocal:
dislocation velocities are stored in the state, so we actually now have three "parts" of the state, the basic states that are updated by "constitutive_dotState" come first, then the dependent states that are calculated by "constitutive_microstructure" follow, and finally we have a last part reserved for other variables that just use the memory reserved by the state array and are updated somewhere else.

constitutive:

LpAndItsTangent does not need the full state, but only the local state, so changed that at least for the nonlocal constitutive law
2011-11-04 13:12:17 +00:00
Christoph Kords 9d1bc584d0 corrected stress integration scheme: now use norm(Lpresiduum) as a target function for Armijo's rule instead of whole tensor Lp; also corrected the guess for the improvement in Lp 2011-11-04 12:57:12 +00:00
Christoph Kords ca3d21a3b6 Depending on which state integrator one uses for the stiffness calculation, the initial state has to be chosen accordingly: e.g. for FPI choose last converged state, but for explicit RK choose converged state from start of increment (in case of explicit euler no state integration at all, but only stress integration). For this purpose we also need to remember "Fe" which now follows the cutbacking procedure as it is used for "Fp". 2011-11-04 12:44:50 +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

2011-11-02 14:38:42 +00:00
Claudio Zambaldi 447e69019c Introduced environment variable DAMASK_ROOT.
It is set in the DAMASK root folder by running damask_env.sh
Much needed in the testing routines so far (try ./testing/run_tests.py)
damask_env.sh could also trigger other scripts to get to a working setup after fresh checkout. For example it could run 
./processing/setup/setup_processing.py
./code/setup/setup_code.py
if it finds that we have a fresh checkout.

2011-10-24 16:57:51 +00:00
