Simulating a Diaphragm with Flow Pressure and Variable Area
 

Hey All. I am asked to simulate a geometry in which a fluid exerts pressure on a diaphragm as a result of which the spring (attached to the diaphragm) deflects and the area beneath the spring changes which changes the flow rate. The task is to perform the simulation in such a way as to look for the deflection of the spring, change in the flow-rate , velocity and pressure of the flow all at the same time. Is it possible ?
Need some quick help please. Anticipating for some prompt replies.
Thanks in Advance.
