New question #665379 on Yade: https://answers.launchpad.net/yade/+question/665379
Hi, I would like to understand the way "penetrationDepth" is calculated. For instance, in a simple collision between two identical spheres I've seen that it does not correspond to x1-x2-2*r where r is the radius of the spheres. I've been looking into the code and found for instance in Sphere_Sphere_ScGeom https://github.com/yade/trunk/blob/master/pkg/dem/Ig2_Sphere_Sphere_ScGeom.cpp (line 21) that the distance is shifted by a vector "shift2" which is passed to the function Vector3r normal=(se32.position+shift2)-se31.position; but whose definition I cannot trace back I suspect that this serves the purpose of interlaced force evaluation for runge kutta etc. but I would like to have a confirmation Thanks for any help Andrea -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
