Application
    sonicFoam

Description
    Transient solver for trans-sonic/supersonic for laminar or turbulent
    flow of a compressible gas.

    Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
    pseudo-transient simulations.  The pressure-energy coupling is done
    using the Rusche manoeuvre (isentropic compression/expansion).

    Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
