Application
    foamToStarMesh

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

Usage
    - foamToStarMesh [OPTION] \n
    Reads an OpenFOAM mesh and writes a pro-STAR (v4) bnd/cel/vrt format.

    @param -noBnd \n
    Suppress writing the @c .bnd file.

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

    @param -surface \n
    Extract the surface of the volume mesh only.
    This can be useful, for example, for surface morphing in an external
    package.

    @param -tri \n
    Extract a triangulated surface.
    The @b -surface options is implicitly selected.

    @param -case <dir> \n
    Case directory.

    @param -noZero \n
    Ignore time step 0.

    @param -constant \n
    Include the constant directory.

    @param -latestTime \n
    Only apply to the latest time step.

    @param -time <time>\n
    Apply only to specified time.

    @param -help \n
    Display help message.

    @param -doc \n
    Display Doxygen API documentation page for this application.

    @param -srcDoc \n
    Display Doxygen source documentation page for this application.

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.
