If I have a box of porous media and an inlet pressure on the bottom edge, no slip on the right and left edge, what boundary condition would I need to apply on top edge to allow for mass loss into the environment given the velocity profile and pressure at this edge are unknown?

Hi,

Is the environment you are talking about atmosphere? Then did you try fixing at atmospheric pressure (Dirichlet)
