2 - applyForceAtContactPoint cannot be used in periodic + ScGeom, since > this function needs the wrapped position of each body (in Dem3Dof, wrapped > position is an > attribute, in ScGeom there is no such attribute and we don't want to > define it as it costs cpu).

Why would be working there and not in applyForceAtContactPoint? thanks, Chiara
