Hello, dear foamers,

How to set the velocity boundary condition on a moving outlet with total pressure?

I tried movingWallVelocity and pressureInletOutletVelocity, but the velocity fluctuates (flows in and out) at the outlet every other time step.

Do I need to program a new boundary condition or I can just use some available one?

Anyone can give me some hints?

Thanks!
