Hi,

There is a valve between two chambers. when simulating, the valve should be set to close to open and open to close slowly.

My first try is to simplify the valve movement as suddenly open and close. So I just changed the pressure outlet to wall and wall to outlet.but what happened is if I set that between the chambers, the liquid could not flow from one chamber to another.There should be a better way to slove this problem.

Is there anybody has related experience about this? I would appreciate a lot, if you could help me to figuire this problem out!

Thanks!
