Description
    Solver for a system of any number of compressible fluid phases with a
    common pressure, but otherwise separate properties. The type of phase model
    is run time selectable and can optionally represent multiple species and
    in-phase reactions. The phase system is also run time selectable and can
    optionally represent different types of momentum, heat and mass transfer.
