nie jiayan posted a new comment: Hi, Jan, Thanks for your MWE. It functions well. but indeed when using this method, for a fixed kn, the sphere with a smaller radius will have a larger young, which results in a small critical time step. That's really time-consuming when conduct simulations with a gap-graded specimen. Maybe for a simple linear contact model, like in PFC, we can directly assign the same values of normal and shear stiffness kn ,ks for all the contacts, and the critical time step is depends on the minimum of math.sqrt((mass/kn)) of the particle. I do not know if Yade has the same contact model since I am a novice. So I modified some source code to achieve this simple contact model. -- 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 : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
