Hello,

I am modeling the FSI between an air flow and a flexible structure using the ICFD solver. 

Is it necessary for the ICFD_PART to exactly match the exterior surface of the flexible structure? The pid of the ICFD_PART is referenced in the keyword ICFD_BOUNDARY_FSI. The flexible structure includes many small features such as flanges, bolted joints, and other details. I am considering defining the ICFD_PART using a simplified geometry. In this case, will the solver correctly interpolate the load and displacement between the fluid and the structure? 

Kind regards
