fc7b4d6471
new function stateJump, which takes care of immediate changes in the state (deltaState); this introduces discontinuities in the state evolution; therefore this is always and only once done after each integration step, so no evaluation of deltaState for intermediate steps of e.g. the Runge-Kutta integrator; otherwise integration becomes a pain without significant gain in accuracy
...
deltaState now successfully tested for nonlocal model; was not correct for integrators 1,4,5 before
2012-06-06 15:11:30 +00:00

2012-05-20 13:57:35 +00:00
5b02d4e8eb
dipole dissociation and formation by change in stress as new mechanism in deltaState; had to add dipole height to state variables, which is however updated by deltaState instead of microstructure; alternatively microstructure had to know the current stress state

abbae76c51
instantaneous jumps in the state by constitutive_deltaState are now incorporated for all state integrators. still they (should) not influence the result, since all constitutive laws simply return zero for the deltaState
2012-05-17 15:25:21 +00:00
351c2c6e65
deltaState depends on the current state, no the state at the beginning of the timestep

2012-05-17 11:04:22 +00:00
a54439e3b5
dotState does not have to be reset to zero. this is a remnant from older versions when the dotState for the nonlocal model used to be updated by the neighboring integration point
2012-05-16 15:35:14 +00:00
84d4652a07
all constitutive modules now contain a new function "deltaState", which in the future allows to have an instantaneous and incremental change of the state (additional to the rate based evolution with dotState).

Dead dislocations are treated the same as mobile dislocations for the flux part though they do not contribute to slip. By that the pileup of dead dislocations is able to diminish with time (kinetics are the same as for the glide part; this is not correct but gives valuable results). Also remobilization of dead dislocations at neighbor is taken into account for flux.
2012-03-14 15:32:50 +00:00

minor changes, substituting implicit type conversions with explicit ones
2012-02-14 12:17:47 +00:00
30c55c3142
added check for unknown keywords again (in agreement with Philip ;-)
...
indeed 'constitution' and '/nonlocal/' are the only keywords which have to be ignored, since they are parsed elsewhere
2012-02-14 09:22:37 +00:00
9b73cb3c65
removed parameter check complaining about unknown keyword as default case. there are just too many keywords that do not trigger a variable assignment to cope with them (e.g. /nonlocal/, constitution, etc.)
...
I suggest to kill similar logic from other files if present somewhere...
2012-02-13 23:30:59 +00:00
c786336af3
reordered (and partly redistributed) error message identifiers, deleted those which are not in use anymore.

changed Peierls stress to more realistic values for fcc
2012-02-03 13:12:45 +00:00
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.
2012-02-03 12:50:54 +00:00
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
2012-02-03 12:37:52 +00:00

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

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)
2012-01-26 13:50:00 +00:00

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
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.

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

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

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

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".

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

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.

ip volume is now based on the determinant of F. "mesh_ipVolume" represents the initial volume and is multiplied with det(F) wherever the current volume is needed. Since this works for all solver types, the "volume" output in crystallite is now also correct for spectral method and abaqus.

* 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

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

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

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

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
97a0146672

cd5407b08b
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

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!!!

2011-01-05 16:11:51 +00:00
096a4803b0
some polishing concerning openMP initialization
...
number of threads is now written to *.out file
2010-12-02 11:04:29 +00:00
36f27edd75
1. Adding more comments
...
2. Changing 'subroutine' into 'function' for optimizing the computation time
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
15728d3305
enclose wall time measurement for dotState and dotTemperature function by CRITICAL construct
2010-11-19 17:19:03 +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
2010-11-04 18:18:01 +00:00
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
0dd99cb965
lattice: (re)introduced _symmetryType function to replace unsafe lookup array
...
numerics: polishing
mpie_cpfem_marc: polishing
..powerlaw: aware of symmetryType function
crystallite: aware of symmetryType function, smaller leapfrog acceleration
IO: new warning 101
CPFEM: range of odd stress is now -1e15...+1e15, H_sym is used for stiffness
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.

4c20daa00d
state loop count was wrong for adaptive euler integration
2010-10-28 12:22:17 +00:00
17812c1f9e
added raw output, gmsh output is still included
2010-10-27 17:15:49 +00:00
9320d48305
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
changed calculation to small strain/cauchy stress
2010-10-20 11:27:10 +00:00
da35eaa8a1
changed spectral algorithm to version proposed by Ricardo 2001 (using tau_field instead of stress_field).
...
Still using largestrain-formulation
2010-10-20 09:27:47 +00:00
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
fffe731447
* had to correct nonlocal slip system compatibility and flux calculation. last update gave wrong results.
2010-10-15 13:19:26 +00:00
61f8a5fcbe
corrected UpperCase "SolidSolutionStrength" in config file parsing.
2010-10-15 12:59:00 +00:00
3c502561ee
added matrix multiplication 3333x33 to math.f90
...
added some parameters for spectral method to numerics.f90 (tolerance)
changed error message concerning spectral method in IO.f90
corrected calculation of stress BC in mpie_spectral.f90
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.
...
example:
OLD: reading 5 results in 2^5=32 FPs
NEW: reading 33 results in 33 FPs
2010-10-01 10:42:15 +00:00

...
(needs comparison to former set, which is potentially wrong)
2010-09-30 17:31:19 +00:00
b85f9b0770
material.config: changed texture of microstructure 1 from 1 to 3, because 1 needs a ODF file which is not in the repository and makes the one_element_model.proc complain.
2010-09-30 12:55:38 +00:00
a8dfdc6487
added _mul33xx33 double contraction: A_ij * B_ij = scalar

6ea8623f65
added functions math_mul33x3_complex math_Plain99to3333 to math.f90.
...
mpie_spectral.f90 uses both functions

math_mul33x3_complex is used for equilibrium check in fourier space
also did some cleaning up on mpie_spectral.f90
2010-09-22 12:04:43 +00:00

2010-09-07 09:06:02 +00:00
a3c92061f9
1) terminallyIll was reset before FE did cutback --> useless extra calculations of same problem over and over...
...
2) local stiffness calculation is now standard for non-local grains
3) stressLoopDistribution discriminates between (a) central solution and (b) stiffness perturbation
4) debugger is switched on as standard... (but verboseDebugger not!)
2010-09-06 16:06:41 +00:00
00922705eb
now using current average stiffness for reference material stiffness

2010-09-01 08:05:11 +00:00
85febf0803
added fftw3 as fft(library will not versioned, should be in a linkable folder) , did some corrections on the code, splitted main file up (allows use of makefile), added makefile
...
changes on mpie_spectral.f90:
new structure, changed variable names, now using defgrad instead of disgrad, cleaned up, removed augmented Lagrange.
ToDo: Implement Augmented Lagrange again (but then a working version), implement Large strain, think about complex-to real-transform backwards, try to implement MP-support
2010-08-27 16:39:38 +00:00

rather perturb all components at once (and optionally decrease the frequency of the Jacobian update with the iJaco parameter) than perturbing only a single component per cycle
2010-06-17 06:32:56 +00:00
1c72439350
first shot at init with CPFEM_general

0c5bc83469
in nonlocal_microstructure: at the model surface the excess density is now extrapolated from opposite neighbor instead of assuming zero density; this results in better modeling of the dislocation stress at the surface
...
restructured nonlocal_dotstate, to be able to easily switch on and off particular effects in the microstructure evolution
nonlocal_dotstate now enforces a cutback when single density runs the risk of becoming negative; in the case of a state already below the relevantState dotState is set to zero
introduced two new output variables: rho_dot_edge and rho_dot_screw

new numerics parameter "defgradTolerance" replaces "relevantStrain" in cpfem, since "relevantStrain" is also used in crystallite but in a different context.

"defgradTolerance" gets the same standard value as "relevantStrain" so calculations should be consistent with older ones

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)

- While math has everything in radians, post results eulerangles and axisangle are given in degrees.

...
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.

constitutive_nonlocal:
...
- reworked contribution of immobile dislocation density for rate equations
- flux is now calculated on the basis of interpolated velocities and densities at the interface; both incoming and outgoing fluxes are considered, so every material point only changes his own dotState
- dislocation velocity is now globally defined and calculated by subroutine constitutive_nonlocal_kinetics; the subroutine is called inside _LpAndItsTangent as well as _microstructure; therefore, microstructure now needs Tstar_v as additional input; in the future one should perhaps create a subroutine constitutive_kinetics that calls constitutive_nonlocal_kinetics separately, to clearly distinguish between microstructural and kinetic variables
- better use flux density vector as output variable instead of scalar flux values for each interface
- added output variables internal and external resolved stress
crystallite:
- added flag to force local stiffness calculation in case of nonlocal model
- misorientation angle is explicitly set to zero when no neighbor can be found
debug:
- added flag "selectiveDebugger" that is used when debugging statements should only affect a specific element, ip and grain; these are specified with the new variables debug_e, debug_i and debug_g

Additional feature to the RGC scheme: The volumetric consistency constraint. This is implemented by penalizing any volumetric discrepancy which occurs due to severe relaxation. The penalty for volume inconsistency is described using a power-law model. The setting for this function can be done in the numerics.config via three new parameters, i.e., maxvoldiscrepancy_RGC, voldiscrepancymod_RGC and discrepancypower_RGC. For monintoring, an extra output variable in prescribed in the material.config in the RGC section, namely "(output) volumediscrepancy".

- corrected change rate for "dipole size" dupper
- corrected term for dipole dissociation by stress change
- added transmissivity term in fluxes which accounts for misorientation between two neighboring grains (yet hardcoded transmissivity according to misorientation angle)
- added more output variables
constitutive:
- 2 additional variables "previousDotState" and "previousDotState2", which are used to store the previous and second previous dotState (used in crystallite for acceleration/stabilization of state integration)
- timer for dotState now measures the time for calls to constitutive_ collectState (used to reside in crystallite_updateState, which is not critical in terms of calculation time anymore)
crystallite:
- convergence check for nonlocal elments is now done at end of crystallite loop, not at the beginning; we simple set all elements to not converged if there is at least one nonlocal element that did not converge
- need call to microstructure before first call to collect dotState for dependent states
- stiffness calculation (jacobian): if there are nonlocal elements, we also have to consider changes in our neighborhood's states; so for every perturbed component in a single ip, we have to loop over all elements; since this is extremely time-consuming, we just perturb one component per cycle, starting with the one that changes the most during regular time step.
- updateState gets a damping prefactor for our dotState that helps to improve convergence; prefactor is calculated according to change of dotState
IO:
- additional warning message for unknown crystal symmetry

Introduction of a numerical viscosity into the RGC scheme to improve the convergent behavior and the numerical stability of the scheme (see: homogenization_RGC.f90). These changes have been incorporated in all related subroutines (homogenization.f90, IO.f90, numerics.config and numerics.f90).

(2) stepIncreaseHomog and stepIncreaseCryst := step increase when calculation for substep converge (was also hardcoded).
introduced a possibility to choose different finite difference scheme, i.e., forward-, backward- and central-difference, for computing grain numerical tangent. note that central-difference scheme will slow down the computation significantly. please use it only if necessary.
parameters to set these new features have been included in numerics.f90 and numerics.config, whereas corresponding error messages have been introduced in the IO.f90

sorry, back to the previous version. grain deformation output is part of crystallite.f90, no longer done by homogenization. material.config reflects the changes.

added possibility to output individual grain deformation gradient in homogenization_RGC.f90 and the homogenization.f90 has been modified accordingly. see material.config for the key-words to output the individual grain deformation gradient in the homogenization block.

- poisson's ratio is now calculated from elastic constants
- microstrucutre has state as first argument, since this is our output variable
- periodic boundary conditions are taken into account for fluxes and internal stresses. for the moment, flag has to be set in constitutive_nonlocal.

constitutive:
- passing of arguments is adapted for constitutive_nonlocal model
crystallite:
- in stiffness calculation: call to collect_dotState used wrong arguments

- added some output statements
constitutive:

crystallite:
- some functions and subroutines needed additional input variables for passing to constitutive
- call microstructure with current temperature, Fp, Fe, not "sub0" values
- show number of IPs, that are "onTrack" instead of those not "onTrack"

b09b2b17f3
convergence of state in crystallite is now tested as follows:
...
(state < relevant state) or (residuum < relative tolerance * state)
since the relevant value for the state variables depend on their nature and can vary by large scales (e.g. volume fraction: 1e-10, dislocation density: 1e5) it is not possible to set a unique value. instead the constitutive law has to decide what is relevant. therefore, all constitutive laws now read in parameters from the material.config that determine the values for relevantState [@luc: in dislobased law relevant State is for the moment generally set to 1e-200, so no additional parameters necessary in material.config. if you also want this feature, we can still implement it, no big deal]
- added sanity checks in constitutive_nonlocal.f90
- corrected coordinate transformation for backstress calculation in constitutive_nonlocal.f90
- corrected equations for evolution of dipole dislocation densities (athermal annihilation and formation by glide)
