Description
    Transient solver for laminar or turbulent flow of weakly compressible
    fluids for low Mach number aeroacoustic applications.
 
    Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
    pseudo-transient simulations. The RCM interpolation is used as in
 
    \verbatim
        Knacke, T. (2013).
        Potential effects of Rhie & Chow type interpolations in airframe
        noise simulations. In: Schram, C., Dénos, R., Lecomte E. (ed):
        Accurate and efficient aeroacoustic prediction approaches for
        airframe noise, VKI LS 2013-03.
