Question #681180 on Yade changed:
https://answers.launchpad.net/yade/+question/681180

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

if you print b.state.angVel, it is set properly. The problem is somewhere in NewtonIntegrator not applying angular motion for fixed aspherical bodies [1], where angMom is is taken into account, but not angVel [1]
Feel free to open a bug report.

A **workaround** is to set
b1.aspherical = False
than the polyhedron does rotate.
I am not sure with the consequences, but **I think** it should be OK for fixed bodies..

cheers
Jan
