No, rhoCentralFoam can solve for both the inviscid and the viscous flow. Check the code (see flag "inviscid"). The grid seems good....

In rhoCentralFoam, what is giving troubles to you seems to be the energy equation, given the error message you obtain. Is it converging before the crash? Are you performing inviscid runs in...

If there is no bug, it might be related to how the equations are discretized, as I said before, but it's just a guess. I'd suggest to use codes with the conservative form of the equations for...

To exclude a possibility: in your run in rhoCentralFoam, did you set thermoPhysical properties to the same data you report for air (some tutorials use the normalised gas)? Best,

Hello, I'm sorry to answer with a question: what does rhoSonicFoam does? The major difference I can see between the solvers you used is that rhopSonicFoam and rhoCentralFoam solve for conserved...
