Reaction Force calculation in solid part in 2-way FSI simulation with CFX
 
Hi Everyone,

I am doing an FSI simulation where I apply a displacement over a certain area of a pipe-like structure (where there is no fluid) and I want to see the behavior of the fluid and calculate the required force. Find attached a view of how my worbench looks like.

The question is how can I calculate the force that I have to exert on the solid part. I have read that you can calculate the force on the fluid surfaces using for instance force_x()@NameOfSurface but doing so with the name of the surface where the displacement boundary condition is applied returns 0 when it can't be that.

Thank you very much!
