Class
    Foam::generatedFaceZone

Description
    faceZone selection or generation class

    The faceZone is either looked-up from the mesh or generated by a
    zoneGenerator and stored locally.

Usage
    Examples:
    \verbatim
        // Select the faces within the faceZone rotor
        faceZone rotor;

        // Select the faces within the given box
        faceZone
        {
            type        box;
            box         (3.48 -0.1 -0.1) (3.5 0.1 0.1);
        }

        // Select the faces representing the given plane
        faceZone
        {
            type        plane;
            point       (0.41 0 0);
            normal      (1 0 0);
        }
    \endverbatim
