Rotation of a flexible body

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.

Hi ewold,

  It can be done by specifying remote points. Check out this useful article that describes how to do this.

One more way is use of general joint. Free all the DOFs for the joint and then measure the relevant rotation.
