I am trying to model a tube closed at the two ends by 2 plates. The cavity enclosed by the two plates and the tube is filled with fluid. I fix one end and apply a force to the other end. The tube is a very flixible material and thus all the force should be present as a pressure detected by the fluid.
When I try to do 2-way-FSI in ANSYS WB with CFX, all the force is taken up by the tube and none by the fluid. any suggestions?
