Question #233320 on Yade changed: https://answers.launchpad.net/yade/+question/233320
Bruno Chareyre posted a new comment: @Mattias, I don't have precise experiments to suggest unfortunately. I'm only speculating. I've read you *.ods sheet (thanks). If I guess correctly, what it shows is that indeterminacy is of similar amplitude on max force if you compare "double" runs between them and "quad" runs between them. My interpretation is that any small difference between two states gives completely different results after some time but at the same time the result is bounded by physical constraints. So what you see is not the magnitude of rounding errors, it is the range of physically acceptable configurations, as if indeterminacy was deeply rooted in the problem. Now the thing that doesn't fit in this picture is #25, where you find different behaviour for the bulk material. A question is if the difference in std deviation is obtained with a sufficient number of results. It may be just luck that you get a smaller one with quads. -- 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 : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
