Default Combined linear-angular motion (flow driven)

nskelly is on a distinguished road

I am working on project where a bileaflet valve is moving linearly up and down and should open to a certain angle. When it moves down the pressure should close the valve.

I am having trouble getting the valves to open using flow driven motion. The valves open at random times and either one is open and the other is not. This results in unphysical pressures for the device.

I have attached a image of the problem.

I am using pressure BCs at inlet and outlet, k-epsilon model, intelligent solution.

Any advice would help.
