Dear all,

I am simulating a pressure vessel with one inlet and one outlet and both of them are with valves. The experiment procedure are as follows.

1. Keep the outlet valve closed, and open the inlet valve, measure the pressure inside the vessel. When it reaches 3bar, closed the inlet valve.
2. Keep the inlet valve closed, and open the outlet valve. I have measured that the pressure at the outlet valve is roughly around 0.15bar.
3. Continue with the procedure 1 ,when the internal pressure reaches 3bar, open the outlet valve.

I am using a coupled structure-fluid model to simulate the strain distribution of the pressure vessel. Any suggestions how to set the BCs?

Many many thanks.
