Question #693506 on Yade changed: https://answers.launchpad.net/yade/+question/693506
Jérôme Duriez posted a new comment: You can also realize that geom.normal is from i.id1 to i.id2 [1] (whether i.id1 is b.id = 10 or 20 in a 10-20 contact being indeed collider-dependent), and that contact forces are from i.id1 onto i.id2 [2] This insures the given sign for the dot product, in accordance with the repulsive (compression) or attractive (tension) nature of the force.
