is sonicFoam better in convergence than rhoPimplefoam or rhoCentralFoam?
 

Im running with sonicFoam.what kind of solver is this in compare with rhoCentralFoam and rhoPimpleFoam?
has had anyone any experience with it?
in my experience it more stable than others.why?can anyone clarify?

Hello ehsan,

I have found the same thing, and I do not know why. I have a harder time getting a converged solution from sonicFoam, and the simulation takes more time to complete, but the results I get from the other two have strange artefacts and produce poor results.
