Application
    star4ToFoam

Description
    Converts a Star-CD (v4) pro-STAR mesh into OpenFOAM format.

Usage
    - star4ToFoam [OPTION] <ccmMesh>\n
      convert pro-STAR mesh to OpenFOAM

    @param -ascii \n
    Write in ASCII format instead of binary.

    @param -scale <factor>\n
    Specify an alternative geometry scaling factor.
    The default is @b 0.001 (scale @em [mm] to @em [m]).

    @param -solids \n
    Treat any solid cells present just like fluid cells.
    The default is to discard them.

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

    @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
    - baffles are written as interfaces for later use
