Class
    Foam::OppositeFaceCellWave
 
Description
    Version of FaceCellWave that walks through prismatic cells only.
 
    Used to determine mesh structure. In the front walking routines
    (faceToCell and faceToCell) it
    - walks across prismatic cells only
    - and only to a single opposite face
 
    Notes:
    A cell with a split faces will be marked but not walked through (since
    there is no single opposite face.
