Question #629486 on Yade changed: https://answers.launchpad.net/yade/+question/629486
Status: Answered => Open Ed Carlos Alves Rocha is still having a problem: I did the Cylinder example, however, I do not know give the imput of collision detection for this example. Can you take a look and see what impact collision between the cylinders and the wall?
