Hi Foamers,

I want to simulate a flow in a nozzle wich can be subsonic or supersonic. I have defined a nozzle thanks to blockMesh, I use sonicFoam and now I have some difficulties to choose the boundary condition's.
Currently I have:

Inlet:
p : totalPressure
U: pressureInletVelocity (value uniform(0 0 0) )
T: totalTemperature

Outlet:
p: waveTransmissive
U: zeroGradient
T: zeroGradient

You can see my 0 file if you want more informations

Thank you for all recommandations

Please I need some help

My simulation doesn't give me good results so I would like to know if the boundary conditions are ok or not.

Thank you
