Status: Answered => Open weijie is still having a problem: Thanks to Jan and Bruno, >how to enlarge the polyhedron? For polyhedron-polyhedron,I found that in Ig2_Polyhedra_Polyhedra_PolyhedraGeom[6]the rotation matrix is multiplied by interactionDetectionFactor to enlarge the two polyhedrons.This may be helpful in my case to enlarge between 2 polyhedrons.But for the interaction between sphere and polyhedron,how should I deal with it? >How to set stiffness of such distant interaction? For CPM,I found that Kn and KS are calculated in Law2_ScGeom_CpmPhys_Cpm[7].The values of kn and Ks depend on crosssection and reflength. For polyhedron - polyhedron, polyhedron - sphere, is their crosssection calculation still pi * Rmin ^ 2[8]? If so, is the value of radius should multiplied by interactiondetectionfactor?
