Question #686076 on Yade changed: https://answers.launchpad.net/yade/+question/686076
Chareyre proposed the following answer: Hi, I would support 2) for the sake of performance, but there's also 3) fix myRotation() since obviously imposing rigid body motion needs to impose 'vel' too (spin*pos), not just 'angVel'.
