Christoph Kords 3dfdbaff5b Fixed wrong indices in tangents dT_dFe and dFe_dLp, which however luckily did not have any effect in the perturbed stiffness since they were transposed such that the double contraction of both remained unchanged.
In contrast, the analytical jacobian will probably be affected by this change!
@Pratheek: Can you check with me how this can be fixed?
2014-01-22 08:38:13 +00:00
Martin Diehl 6fa9ed8f48 homogenization: added enums and sourced allocation for RGC, some higher verbosity for isostrain 2013-12-18 07:28:01 +00:00

Martin Diehl 2f7efa2055 introduced named constants for homogenization_type, phase_plasticitiy, and phase_elasticity to replace expensive string comparison. Labels for different schemes need to be stored in material.f90 because they are needed when parsing the config file 2013-11-27 08:04:05 +00:00
Martin Diehl ea664688f8 introduced dummy temperature calculation. 2013-10-18 20:56:10 +00:00
Martin Diehl dc95c82d4a removed temperature integration and corresponding data structures and debugging options
temperature is stored in crystallite, but homogeneous on one IP (not an component (grain) quantity and an input value parsed in by the BVP solver.
introduced heat, a component (grain) quantity which is homogenized before returned to the heat transfer solver.
went ahead with removal of dummy functions in homogenization and constitutive, this time mainly reduced function signatures to reflect actually needed quantities.

Martin Diehl ed47d25adc remove dotTemperature (returned always 0 anyway) to make it easier to replace it with a heating rate funtction
