Question #218111 on Yade changed: https://answers.launchpad.net/yade/+question/218111
Václav Šmilauer posted a new comment: P-wave timestep is actually not correct for clumps. A wave propagates elastically in sphere, but the connection of particles within one clump propagate the wave immediately (infinite stiffness). E.g. clump like (r1=0.1m)--[center-center distance 0.2m]--(r2=0.1m) has 0.4m distance between contact endpoints, but only 0.2m are elastic material. The critical timestep should be multiplied with (elastic_length/geometric_length), in this case 0.5. -- You received this question notification because you are a member of yade-users, which 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
