Class
    Foam::mappedFixedValueFvPatchField

Description
    This boundary condition maps the value at a set of cells or patch faces
    back to *this.

    The sample mode is set by the underlying mapping engine, provided by the
    mappedPatchBase class.

Usage
    \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 |
        interpolationScheme | type of interpolation scheme | no |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            mapped;
        fieldName       T;
        setAverage      no;
        average         0;
        interpolationScheme cell;
        value           uniform 0;
    }
    \endverbatim

    When employing the \c nearestCell sample mode, the user must also specify
    the interpolation scheme using the \c interpolationScheme entry.

    In case of interpolation (where scheme != cell) the limitation is that
    there is only one value per cell.  For example, if you have a cell with two
    boundary faces and both faces sample into the cell, both faces will get the
    same value.

Note
    It is not possible to sample internal faces since volume fields are not
    defined on faces.
