Application
    foamToStarMesh

Description
    Reads an OpenFOAM mesh and writes a pro-STAR (v4) bnd/cel/vrt format.

Usage
    \b foamToStarMesh [OPTION]

    Options:
      - \par -noBnd
        Suppress writing the \c .bnd file

      - \par -scale <factor>
        Specify an alternative geometry scaling factor.
        The default is \b 1000 (scale \em [m] to \em [mm]).

Note
    The cellTable information available in the files
    \c constant/cellTable and \c constant/polyMesh/cellTableId
    will be used if available. Otherwise the cellZones are used when
    creating the cellTable information.
