Application
    rhoPorousMRFPimpleFoam

Description
    Transient solver for laminar or turbulent flow of compressible fluids
    with support for porous media and MRF for HVAC and similar applications.

    Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
    pseudo-transient simulations.
