Question #705007 on Yade changed: https://answers.launchpad.net/yade/+question/705007
Guo, Chang posted a new comment: Dear Karol, Thanks for your reply. I didn't express myself clearly. Assuming such a situation, there is a single sphere, A, and a clump, B, with two spheres, C and D. C and D have an overlapped zone. Normal stiffness between each pair of particles is kn . There is a contact between A and B and the penetration depth is delta. When this contact isn't at the overlapped zone, the normal force should be delta*kn. However, if this contact is at the overlapped zone, the normal force would be calculated twice, that is, 2*delta*kn. It looks unphysical. -- 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
