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:

*** WARNING *** CP = 0.594 TIME= 21:41:04
ANSYS results must be written into the database for Multifield
analysis. The /CONFIG,NOELDB,1 command is ignored.
