ReactingFoam: how to impose non-reflecting BCs at the outlet for subsonic flows ?
 

Hi all,

I'm doing DDT computation with reactingFoam, but, whatever the choice of my outlet boundary condition on pressure and velocity (waveTransmissive, pressureInletOutletVelocity, etc.), I still have a small reflection coming from the outlet BC. I precise that my flow is compressible, but subsonic, which is the most complicated case. Anyone found a solution ?
