Hey Tobit,
I can recommend you either the interpolated Boundaries or the offLattice Bounadries (aka Bouzidi) for turbulent flows. Every local boundary formulation will get instable. For the outlet (pressure) boundary, we don’t have a working offLattice Boundary. (I never get anti bounce back stable for higher Reynolds numbers). So I would recommend you to use the Interpolation boundary for the outlet and the offLattice boundary for the inlet.
Best Marc
