Fluid-Structure Interaction
 

Dear All,

I am working on Fluid-Structure interaction modelling of a simple valve. The objective is that valve will open and then close because of the pulsatile flow at the inlet.
I am able to model complete FSI in ANSYS. However, I also want to include 'rebound' of valve in my model such that when the valve reaches fully open position it will not just stop there, instead it will rebound at that position.
Does anyone know how do I approach ?
I guess I need some kind of virtual spring which gets activated when certain condition is reached such as the angle between initial position of the valve and fully open position reaches X deg.
All I know from literature is that coefficient of resilience is 0.78 between the valve and housing(fully open position).
I would appreciate if anyone can help me here.
