numerics.config is now optional; if this file does not exist in the working directory, standard values from numerics.f90 are used; either way the output file tells which values were taken.
...
added some output to the init subroutines of debug.f90, FEsolving.f90, lattice.f90, material.f90 and mesh.f90.

Tstar_v is now restored at different stages of cutbacking; we need this because preguess of state relies on consistent Tstar_v

added a new module called numerics.f90 which reads in all numerical "parameters" from the file numerics.config (also being added). From now on this file has to be located in the working directory of the FEM-model and has to contain all necessary parameters.

in crystallite_stressAndItsTangent we now update the state first (explicit integration) and then integrate the stress (implicit integration)
...
also inside the stress integration, it is now possible to define the frequency of the Jacobian update oin the LpLoop through iJacoLpResiduum. The frequency of the Jacobian update for the stiffness in the crystallite loop is controlled by the parameter iJacoStiffness.
also updated the corresponding stuctograms in the documentation

data structure of UserOutput (negative values of post result indices...)
...
please note the introduction of size identifiers (N, n_1,...n_m) which allow to more easily parse IPs which happen to have different constitutive laws for different constituent grains.
2009-05-07 17:41:56 +00:00
4f705f524f
major restructuring of code.
...
homogenization as well as constitutive are now free to choose. the runtime got somewhat longer (25% on simple tests) compared to a hardcoded isostrain homogenization. this might be a point of further optimization at a later stage...
please use homogenization_isostrain.f90 as starting point / example for future developments of homog-schemes.
the homogenization scheme now can additionally output certain results. hence, the userdata structure at each integration point now looks like this:
- sizeHomogPostResults
- block of that size containing homogPostResults
then for each grain:
- sizeGrainPostResults
- block of that size containing crystallitePostResults, which consist of:
+ phaseID
+ volFrac
+ Eulers (3)
+ any constitutive post results requested
