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.
 
Note
    - baffles are written as interfaces for later use
