Class
    Foam::mappedMixedFieldFvPatchField

Group
    grpGenericBoundaryConditions grpCoupledBoundaryConditions

Description
    This boundary condition provides a self-contained version of e.g. mapped
    boundary conditions
    - it expects two-way coupling (so the sampled field needs to run the
      same bc)
    - it does not use information on the patch; instead it holds the coupling
      data locally.

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            mappedMixedField;
        field           T;              // optional field name
        setAverage      no;             // apply an average value
        average         0;              // average to apply if setAverage
        value           uniform 0;      // place holder
    }
    \endverbatim

Note
    Supports multi-world operation:

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