Reply To: How to make a zone follows the motion of system coupling?

[Federico]

Hello Audy, 

The short answer is no. When doing 2-way FSI, fluent will pass forces to the structural solver, which will pass back displacements to Fluent. This is done on each cell face in the system coupling interface. Hence, I am not sure which displacement exactly you would want to apply on the Rigid Body zone.

Is there a reason why you want to preserve the zone around the Deck Zone as a rigid body? 

As you have stated, the Rigid Body Zone is meant to assign a prescribed motion to an entire cell zone.
