Martin Diehl 296a5040b9 fixed bug in initialization when reading in material.config.
Fortran does not short-circuit, e.g. (if a>0 .and. b(a) ==c) might cause an out-of-bounds error when a=-1 it'll try to access b(-1)!

Philip Eisenlohr e4ce63d689 switched matrix indices in SlipSlip, SlipTwin, TwinSlip, and TwinTwin such that first index refers to first name and second to second... (used to be transposed for memory efficiency) 2012-11-14 10:22:34 +00:00
Christoph Kords dad9922f54 fixed bug in crystallite_FPI: stateDamper always has to be defined for each grain
added some OMP FLUSH statements were necessary 
replaced openmp do by forall construct where possible; this is much safer and perhaps even as fast for small loops
2012-11-07 15:43:29 +00:00
Philip Eisenlohr 5ad0eda1b6 switched saturation behavior!!
was \dot s_alpha = (1-s_alpha/s_inf)^a h_alphabeta \dot gamma_beta
now \dot s_alpha = h_alphabeta  (1-s_beta/s_inf)^a \dot gamma_beta

current form is consistent with the genmat implementation (and appears to make more physical sense). Kalidindi_etal1992 suggested this form, but altered it to the alpha-one in Bachu+Kalidindi1998... By now, it seems that some groups use alpha, others beta approach.

introduced two new absolute tolerance values for "shears" and "twinFrac" (default 1e-6).

Christoph Kords 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). 2012-05-16 14:43:26 +00:00
Martin Diehl 9a92d343dc added Onurs modified description for tausat in j2 law.

now all modules have their own debug specification.
compiles and runs, I hope nothing is broken
did a lot of polishing
2012-03-08 20:25:28 +00:00
Martin Diehl 79663a7f76 polishing: adding pInt, removing unused use-statements etc 2012-02-21 16:00:00 +00:00
Nan Jia db06c797cd store number of outputs for each instance of the constitution in constitutive_[j2/titanmod/...]_Nouput and use this value to loop over all valid outputs when determining the size of the outputs array 2012-02-14 15:19:59 +00:00
Christoph Kords 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
Philip Eisenlohr 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
Christoph Kords c786336af3 reordered (and partly redistributed) error message identifiers, deleted those which are not in use anymore.
all constitutive as well numerics now raises an error, if an unknown keyword is found in the respective config file
2012-02-13 17:41:27 +00:00
Martin Diehl 156ec4582a polishing, adding _pInt etc. where applicable
post_results now handels zero increment different (like FEM, it is always there even if it is not counted)
2012-02-13 14:18:07 +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
2012-01-31 19:18:55 +00:00
Martin Diehl 80583fefb5 added compilation_info.f90, to store compilation date,time and compiler info in each file

* replaced "dble" intrinsic function by "real" with pReal kind in constitutive_nonlocal.f90
* removed useless line breaks in output of state in CPFEM.f90
2011-04-04 08:34:52 +00:00
Philip Eisenlohr 5c05c5d068 corrected mixed up array size for hardeningMatrices (twin/slip)
added explicit array range 1:lattice_maxNslip/twinFamily
2011-03-24 17:20:35 +00:00
Christoph Kords 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.

Christoph Kords 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.

Martin Diehl 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

Philip Eisenlohr 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
Christoph Kords 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

Philip Eisenlohr 48e642bb15 twin resistance evolution did not use magnitude of shear rate (dot gamma) but the signed quantity... leads to non-physical oscillations of twin resistance. 2009-10-20 12:15:37 +00:00
Philip Eisenlohr 7914f80931 stiffness calculation for structure > 3 was missing: "case(3)" --> now "case(3:)" as in all other constitutive_xyz..! 2009-10-19 14:47:52 +00:00
Philip Eisenlohr 974116808b fixed a potential memory leak for hexagonal structures. added some status output to constitutive_xx 2009-10-15 20:02:52 +00:00
Christoph Kords 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)

Franz Roters bb0840ecb2 constitutive_phenopowerlaw.f90: check for non-zero w0_slip
IO.f90: added respecteive error message

constitutive_phenopowerlaw.f90: first test with automatic file Id
2009-08-31 14:13:10 +00:00
Denny Tjahjanto b25396374a homogenization_RGC.f90 >>> adding some lines, mostly for debugging purpose. no critical change.
constitutive_phenopowerlaw.f90 >>> adding new parameter: constitutive_phenopowerlaw_w0_slip, i.e., the hardening rate exponent.
homogenization.f90 >>> most important change is to add an if-else statement (line 379-380) to switch crystallite_requeted = .false. for already converged material point iteration (el/ip). the rest of the changes are cosmetics and debugging stuffs.
crystallite.f90 >>> similar to homogenization.f90, the most important change is to add additional if-else statement (line 574) in the jacobian (perturbation) loop. now the jacobian calculation will only be performed when crystallite_requested = .true.. the rest is only cosmetic.
2009-08-27 12:10:06 +00:00

Philip Eisenlohr f337847f35 quite some changes:
# non-greedy memory allocation
# generation of outputConstitutive to allow for script-based T16 extraction
# exchange of phenomenological by more general phenopowerlaw
# lattice is based on slip and twin families which can be treated as individual entities (switched on/off, separate hardening, etc.)
# nicer debugging output
# changed some error/warning codes
# plus potentially some minor additional brushes here and there
