Question #171223 on Yade changed: https://answers.launchpad.net/yade/+question/171223
Chareyre proposed the following answer: > I think the velocity after interaction in absolute coordinates should be > 2.48 (=1.67 + 0.81). It is now obvious for me that it should not be like that. Take spheres with initial velocity = 0. This thinking would give after impact v=0+0.81=0.81, i.e. no bouncing and the spheres moving at the same speed as the boundary. This is not what should happen in elastic impacts, clearly. If you need to compare things, then compare relative to relative. I tested without damping. before: v_sphere = -0.068, v_plate=0.250 -> relative_v=0.318 after: v_sphere = 0.567, v_plate=0.250 -> relative_v=0.317 Everything is correct. Please, Vadim, close this question if you agree. -- 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
