Class
    Foam::wedgeFvPatchField

Group
    grpConstraintBoundaryConditions

Description
    This boundary condition is similar to the cyclic condition, except that
    it is applied to 2-D geometries.

Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            wedge;
    }
    \endverbatim
