Description
    Transient solver for compressible flow using the flexible PIMPLE (PISO-SIMPLE)
    algorithm.
    Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
    The code is an evolution of the solver rhoPimpleFoam in OpenFOAM(R) 4.x,
    where additional functionality for CFD-DEM coupling is added.
