Default pressure boundaries allowing inlet velocities
Posts: n/a

I have a model which has a couple of pressure boundaries, these work as outlet boundaries. There is nothing wrong with them, until I mix them with injecting/extracting species, inside the model, then it allows flow in it.

Do you know how to define pressure boundaries, so that they don't let flow in it?

Many thanks

You can't stop inflow through a pressure boundary. If you want a boundary condition which forces outflow, there is outlet and (negative) inlet.
