Class
    Foam::mappedMixedFvPatchField

Group
    grpGenericBoundaryConditions grpCoupledBoundaryConditions

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
        field        | Name of field to be mapped       | no  | this field name
        weightField  | Name of field to use as weight   | no |
        setAverage   | Use average value                | no  | false |
        average      | Average value to use if \c setAverage = yes | partly |
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            mappedMixed;
        field           T;              // optional field name

        value           uniform 273.0;

        refValue        $value;
        refGradient     uniform 0.0;
        valueFraction   uniform 1.0;
    }
    \endverbatim

Note
    Supports multi-world operation:

    +----+                      +----+
    |    |                      |    |
    |    |                      |    |
    +----+                      +----+
    worldA                      worldB
    regionA                     regionB
    patchA                      patchB
