Good evening everyone. please I come back to you because I tried to do a coupled analysis of my system (fluid - transient structure). my piston must move by fluid hydrodynamic forces. I only added an FSI interface for the piston surfaces (in transient structure), but the error is this: not enough stresses appear to prevent the movement of the rigid body. how to handle this ; I would like to impose a maximum distance of displacement of 15mm
