Martin Diehl 2659ee51d4 restart is working for all solvers, but slight deviations still occur. Reason is most probably, that for CPFEM init, a 0s timestep is required which seems to alter the state a tiny bit, leading to small deviations. For AL and Polarization, this is even more severe since the regular call to CPFEM has F-residual as the current deformation gradient, however the init step uses only F. 2014-03-25 15:44:16 +00:00
Christoph Kords caca65148d fixed bug in restart: stiffness values that were read from file used to be overwritten by "utilities_constitutiveResponse"
Still not fixed in polarization and AL solver !!!

Pratheek Shanthraj 50db944c0c reworked phase field interface to damask spectral solvers. now specify 'thermal a b c' or 'fracture a b c' to activate either phase field where a b c are the initial value, diffusion coefficient and mobility respectively.
Right now only thermal and fracture phase fields implemented and only in the basic petsc solver

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

Martin Diehl 7b87987751 introduced option for regridding to numerics.f90, working as follows:
first cut back is tried if material point model oder BVP solver does not converge.
If no regridding is enabled after max cut back, in case of non-converged material point the simulation stops and in case of non-converged BVP solver it continues.
set regridMode to 2 to enable regridding if BVP solver OR materialPoint model do not converge,
set regridMode to 1 to enable regridding if materialPoint model do not converge, non-converged BVP solver will be ignored as in the standard case.
For regridding, the load case need to have a restart freq set.

enabled restarting for Basic PETSc variant
