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 81531097f1 changes on convergence tolerances of AL and Polarisation, switched back to immediate correction of stress bc but only when last two average stresses are close to each other (cosine decay) 2013-07-30 15:32:55 +00:00
Pratheek Shanthraj 03d8f14a98 introduced dynamics for high strain rate simulations. so far only works for materials with homogeneous density. the density is read in as an optional argument in the load file using the keyword 'den' or 'density'. if density > 0 then inertial terms are added to the stress equilibrium. an implicit euler time discretisation is used to calculate the inertial terms.
dynamic problems are length scale dependent so make sure the geometry size is meaningful (1 m^3 or N m^3 for example is too big for a RVE!).

not specifying a density (density = 0) will perform a quasi static simulation as before.

Martin Diehl c6a79d2b3d divergence_correction for basic solver variants has now 3 possibilities:
0: uncorrected, slope per sidelength (physical dimension) e = res/dim
1: corrected by sidelength, slope per unitlength          e = res/1
2: corrected such that distance between FPs               e = 1

alway regarding the medium length of x,y,z direction
