Class
    solidWallMixedTemperatureCoupledFvPatchScalarField

Description
    Mixed boundary condition for temperature, to be used by the
    conjugate heat transfer solver.
    Both sides use a mix of zeroGradient and neighbourvalue.

    Example usage:
        myInterfacePatchName
        {
            type                solidWallMixedTemperatureCoupled;
            neighbourFieldName  T;
            K                   K;
            value               uniform 300;
        }

    Needs to be on underlying directMapped(Wall)FvPatch.

    Note: runs in parallel with arbitrary decomposition. Uses directMapped
    functionality to calculate exchange.
