Hello,

I'm trying to simulate the flow in a pipe containing a bi-leaflet valve whose movement (only the rotation angles of the leaflets) is driven by the flow. I'm using the Immersed Solid method for the moving bodies and the CFX Rigid Body solver for the 1 DOF movement.

I don't know how to constrain the angles of the leaflet to just between the valve opening and closing angles (90 and 40 respectively). There are options to add external Forces/Torques on the leaflet domains using expressions but I'm not sure if this is how I can get more control over the valve. Any advice on how to accurately calculate the forces to make the valves open and close at the right times, and constrain the angles would be appreciated.
