The mentioned discussion was regarding Fluent not Mechanical. I was initially not sure from what side you intended to drive the motion.

Rotational velocity is a setting in Mechanical that solves the problem in rotating frame. It does not move the Mechanical mesh.

You have to find a set of boundary conditions that makes sense for your problem. Think about what the model is doing and what is being transferred (i.e. displacement) in which direction. This is the only way to solve such problems - the model is on your side so you're in the best position to do this. If something particular is not working as expected then you can ask us. Rotational velocity does not move the mesh. This is not a problem this is a lack of product knowledge that can be addressed by reviewing the help manual.

We can't set the problem up for you, this would be a consulting project for a commercial customer. It takes time to be done properly and can't be done over a forum. I'm sorry.
