Adaptive fixedValue/zeroGradient
 

Hi foamers,

I would like to simulate the flow into a nozzle. This flow can be subsonic, full supersonic or with shock. I use sonicFoam and my boundary conditions seem to be good.
At the outlet, I have waveTransmissive for the pressure but I would like to use fixedValue for the subsonic or shock case and zeroGradient for the full supersonic flow with the same code.
Is it possible?
My problem with waveTransmissive is the parameter linf. I don't know how to choose this parameter so I would like to avoid it
I don't find the changes I have to make and where make there.

Thanks a lot

Valentin
