FSI Question
 
IS FSI possible with multibody having some relative motion in ANSYS.

In my analysis, I started ANSYS Transient Module. The analysis I am doing consist some relative motion between two body, one is fixed and one has revolute joint. I am analysing how this relative motion will affect the flow around it.

The ANSYS solver is run first and then CFX. When I setup everything and run the ANSYS solver gives this error:
