Thanks, it works! Forcing displacements (you can use both TranslationEngine or JumpChangeSe3 __btw,I would really change the name for the latter__), and fixing DOS's as to assign a constant velocity actually works (so for everyone interested in testing a contact law properly this is a good way to do that). cheers, Chiara > > > B > > _______________________________________________ > Mailing list: > https://launchpad.net/~yade-users<https://launchpad.net/%7Eyade-users> > Post to : [email protected] > Unsubscribe : > https://launchpad.net/~yade-users<https://launchpad.net/%7Eyade-users> > More help : https://help.launchpad.net/ListHelp >
