Status: Open => Answered Jan Stránský proposed the following answer: Hi Wang, thanks for the script, it is a bit clearer now. But next time, please try to make it Minimal and Working (e.g. I cannot try it because I don't have 'cccc.gz' file As I wrote in previous answer, changing material of particles has no effect on existing interactions. ... O.step() ... creates interactions ... b.mat.young = whatever # has no effect on existing interactions, only on newly created you have two options: 1) edit IPhys instead of material, but then you should know the model to change everything necessary: for i in O.interactions: i.phys.E = 1e20 i.phys.kn = i.phys.E * i.phys.crossSection / I.phys.refLength 2) change b.mat.young before the first O.step() is called Aslo note that for very high stiffness, you should modify accordingly your O.dt, otherwise the simulation "explodes". cheers Jan -- 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
