I'd need some help for setting boudary conditions. I simulate drainage in a porous media. I imposed the atmospheric pressure as BC in outflow (like a drain). For velocity, I imposed pressureInletOutletVelocity boundary condition. I was wondering if there would be a boundary condition that replicates a concentrated pressure drop at the outflow, as though the drain was less efficient. Thank you!
