Hi, I'm somewhat new to CFD and openfoam. I was hoping someone could advise me on whether I can run this simulation in openfoam and what the best solver would be.

I want to study the flow of a compressible gas through a box with a simple inlet and outlet arrangement. The problem is that the Knudson number may be as high as 0.04 (the mean free path is not perfectly known). I've been using sonicfoam but I've read that this isn't the best solver to use. Could someone recommend a better one to use in this situation?

Try rhoCentralFoam for compressible calculations. It is a good solver if your fluid follows the basic "continuum assumption" at all times.
