Eliminating farfield boundary reflections in supersonic simulations
 

Hi,

I'm trying to simulate the flow around a wedge in supersonic flow. When running I get reflections from the farfield boundary that I need to eliminate. I have tried using the waveTransmissive type but have had no luck.

I'm fairly new to OpenFOAM and could use some help

Thanks!

You could also try advective.

I would recommend to put large volume cells near boundaries, so that they can absorb disturbances outgoing from the domain from interest
