Anton, Sergei, it seems you are the ones maintaining and/or using 
facet-sphere code. Are you really aware of this last addition in the 
code? I've seen not much reaction.
I've another uncommited diff (precompute), result of some search-replace 
after changes in ScGeom (in the case of facet functor, it is in fact 
more "nothing found"->"put what should be there").
This alone could explain "hanging" particles and other opened bugs (e.g. 
the "scaleDispT" one). The previous code was (I think) assuming fixed 
facets, which is not exactly relevant for rotating cylinder.
The problem is I still don't know how to reproduce hanging particles and 
I can only guess what sort of laws are used. I don't see myself fixing 
bugs I don't know in some code I don't fully understand...

Cheers.

Bruno
