The problem I am working on is the following:
I have a solid cylindrical structure that encases an irregularly shaped volume of fluid. Within that fluid, there is an irregularly shaped solid held in suspension. I wish to apply a rotational load to the outer solid body and use a FSI to visualize the effects of that load on the fluid flow, and then in turn on the inner solid body.
As far as I am aware, the rotational velocity/acceleration loads are only possible with rigid bodies. How do I go about introducing a rotation to the system without getting excessive distortion errors? Thanks.
