Question #230986 on Yade changed: https://answers.launchpad.net/yade/+question/230986
Bruno Chareyre posted a new comment: The whole clump is indeed considered as a unique particle with a total mass and stiffness. Uncoupled DOFs means that a displacement in the direction x generates a dominant force along x (i.e. the generalized stiffness matrix is assumed diagonal). Be it for a clump or a sphere, this approximation is the same. It is possible to compute without this assumption: compute eigen values of a 6x6 matrix for each body instead of using the diagonal values. It would maybe let a higher coefficient be used: 0.9dt or so instead of 0.8dt, if you think it is worth it. -- 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
