in nonlocal_microstructure: at the model surface the excess density is now extrapolated from opposite neighbor instead of assuming zero density; this results in better modeling of the dislocation stress at the surface
...
restructured nonlocal_dotstate, to be able to easily switch on and off particular effects in the microstructure evolution
nonlocal_dotstate now enforces a cutback when single density runs the risk of becoming negative; in the case of a state already below the relevantState dotState is set to zero
introduced two new output variables: rho_dot_edge and rho_dot_screw

new numerics parameter "defgradTolerance" replaces "relevantStrain" in cpfem, since "relevantStrain" is also used in crystallite but in a different context.
...
"defgradTolerance" gets the same standard value as "relevantStrain" so calculations should be consistent with older ones

first call to hypela2 in inc 0 is done with computation mode 2 (=plain calc), but since rev. 539 the second call was done with computation mode 6 (=only return values) instead of 2. This doesnt work, because computation mode 2 might calculate stress and tangent for all materialpoints, but the mapping from lattice to current configuration is only done for the element/IP that triggers the call.
...
So switched back to the former order of calls which also works for marc2010:
el 1 IP 1 | el 1 IP 2
|
inc mode lovl | inc mode lovl
------------------ | ------------------
0 2 6 | 0 2 6
1 6 4 | 1 6 4
1 4 6 | 1 3 6
1 6 4 | 1 6 4
1 1 6 | 1 2 6
Still to be checked:
according to Franz the lovl order could be different in contact analysis (e.g. starting with lovl 4 instead of 6)

crystallite:

- grainrotation calculation now is done with symmetryID 0, i.e. without symmetry reduction since we want the absolute misorientation.
- While math has everything in radians, post results eulerangles and axisangle are given in degrees.
And: grain rotation seems OK after the previous changes in math module.
