Hi,
Facets have positions which are not necessarily their center of mass, which
makes the contribution mass*distance to inertia not fully consistent.
Note also (1) that discretization=100 is not a good idea since facets
have no volume. Fortunately it seems to work still, for some reason, but
I suggest discretization=0 to be sure.
Note also (2) that if you want to simulate dynamic polyhedra with
clumped facets it will probably not work very well. Better use proper
Polyhedra or clumped Pfacets.
Regards
Bruno
