Class
    Foam::mappedFixedInternalValueFvPatchField

Group
    grpGenericBoundaryConditions grpCoupledBoundaryConditions

Description
    This boundary condition maps the boundary and internal values of a
    neighbour patch field to the boundary and internal values of *this.

    \table
        Property     | Description             | Required    | Default value
        fieldName    | name of field to be mapped | no       | this field name
        setAverage   | flag to activate setting of average value | yes |
        average      | average value to apply if \c setAverage = yes | yes |

Note
    This boundary condition can only be applied to patches that are of
    the \c mappedPolyPatch type.
