Class
    Foam::WallLocationYPlus
 
Description
    Holds information (coordinate and yStar) regarding nearest wall point.
 
    Used in VanDriest wall damping where the interest is in y+ but only
    needs to be calculated up to e.g. y+ < 200. In all other cells/faces
    the damping function becomes 1, since y gets initialised to great and
    yStar to 1.
