Default Non-reflecting pressure bc at outlet
Posts: n/a
Hi all,

due to a high relative Mach number I have some azimuthal pressure fluctuations at the outlet of my domain. The static pressure boundary condition at the outlet forces them to disappear a few grid points before the outlet surface.

Is it possible to impose "non-reflecting" pressure outlet conditions like in fluent?
