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.

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.

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

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

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
