Non-reflecting pressure bc at outlet
 

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?

Yes, FINE/Turbo has the feature of a "non-reflecting" outlet boundary condition to get more accurate results when strong fluctuations in azimuthal direction are expected.
Non-reflecting turbo option is available for pressure imposed, mass flow imposed or Averaged Mach Number.

At the moment its limited to steady computations, please take also note that the outlet patches must be grouped.
