E.g: the rotor is allowed to spin freely depending on the torque exerted by the wind.

Myself and 2 others are undergoing a thesis on VATs but have very little experience with Fluent. We have meshed the blades and surrounding fluid. But are having trouble getting the blades to rotate consistently or run any kind meaningful simulation. Thanks in advance. Tom.

Here are some pictures of the setup i'm attempting to use. I'm assuming it should allow for a preview of the mesh motion, but the desired window does not appear under the 'Mesh Interface' Tab. Any pointers would be much appreciated. Cheers. Tom.
