Jan Stránský proposed the following answer: Hello, > As far as I know, the time-step calculated by the GlobalStiffnessTimeStepper increases with the increasing of the particle density as DEM is discrete, as Robert mentioned, the important quantity is body mass, not its material density you can try: b = O.bodies[someID] print b.state.mass b.mat.density = 100000000 print b.state.mass # has no effect on existing bodies So the correct approach should be for b in O.bodies: b.state.mass *= someFactor 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
