Jan Stránský proposed the following answer:

using PFacets

The main purpose of PFacets (IMO) is to improve this facet behavior.
PFacets consist of vertex/node - edge - facet hierarchy.
If the contact od of sphere-vertex type, the interaction is considered with this one vertex, not any more with more vertices or edges of facets.
If the contact is of sphere-edge type, the interaction is considered with this one edge, not any more with more facets.
Finally the sphere-face type of contact is handled naturally.

So for this problem, pfacets are worth to try at least.

cheers
Jan
