I have run 3M timesteps without any problem.
Please update the script to be MWE also w.r.t time (making the problematic
interaction in the first or a few time steps).

probably not "as it is".
If you had fewer Law2s, it could be feasible.
In the case Yade could not find the Law2 exactly matching given IGeom and
IPhys, it tries to use one based on igeom and iphys base classes (at least I
think so, but I am not sure :-).
In your case, it finds a lot of matches (since ScGeom is base of
GridCoGridCoGeom and ScGeom6D and FrictPhys is base of CohFrictPhys and
MindlinPhys) and do not know what to do, therefore ending with the ambiguity
error.
A solution is to add another Law2, exactly matching GridCoGridCoGeom and
MindlinPhys.
Internally, it can just call any other Law2.
This way, the dispatch would not be ambiguous.
However, this solution needs modification of source code..
cheers
Jan
