How to impose an initial angular velocity on a moving/free particle?

I've tried several ways to impose an initial angular velocity on a free polyhedron but they do not work well as commented in the script and below. Please help me with this. Thanks!
Here are things I've observed: [In the code below, I simulate 2 polyhedrons, poly1 is free and has an initial velocity while poly2 is fixed.]
If I directly use state.angVel or utils.setBodyAngularVelocity to impost an angular velocity on both polyhedrons, nothing happens to poly1, I could observe no rotation but just transnational move. However, I could observe rotation on poly2, which is fixed.
My question is that I want to apply an initial angular velocity on a free polyhedron and see how the initial angular velocity affects its collision with another particle.
If I just fix a polyhedron, and apply both the linear and angular velocity, then I could not observe how it collides with another particle and how the post-impact behavior look like since the fixed one will simply penetrate through another particle, which is not what I want.

##Directly assigning the angular velocity- Not imposing initial angular velocity- No rotation for the free one but the fixed one will rotate
#O.bodies[0].state.angVel=Vector3(1,1,0)
#O.bodies[1].state.angVel=Vector3(1,1,0)

## using: "utils.setBodyAngularVelocity" - Not working for non-fixed bodies(poly1) but working for poly2
utils.setBodyAngularVelocity(0,5*Vector3(1,1,1))
utils.setBodyAngularVelocity(1,5*Vector3(1,1,1))
