Hi all,

Is it possible to have a pressure boundary condition that guarantees inflow? I'd like to explain in more detail. I have a jet simulation where I'm attempting to simulate entrainment of the jet air from behind the jet. Unfortunately, at the boundaries at the to and bottom of the domain, where the flow should be coming into the domain, the flow instead goes out of the domain. I have set the BCs at this domain to be the same as for outlets, i.e., Zero velocity gradients and zero pressure. It was my hope that the velocities would settle to their correct value over the course of the simulation. However instead I ran into the problem just described. I'd appreciate some insight if possible.

Sincerely,
