Dear Hongfu, As things stand we have only been developing VIV capabilities for quasi-3D formulations. We do not currently have a complete infrastructure for fully 3D flow induced vibrations. Regards, Spencer.

I have read the user-guide and found that the "MoveBody" could do this, but "this force type is only supported for the Quasi-3D incompressible Navier-Stokes solver". What can I do? Any help would appreciate!
