Class
    solidWallMixedTemperatureCoupledFvPatchScalarField

Description
    Mixed boundary condition for temperature, to be used by the
    conjugate heat transfer solver.
    If my temperature is T1, neighbour is T2:

    T1 > T2: my side becomes fixedValue T2 bc, other side becomes fixedGradient.
    

    Example usage:
        myInterfacePatchName
        {
            type                solidWallMixedTemperatureCoupled;
            neighbourRegionName fluid;
            neighbourPatchName  fluidSolidInterface;
            neighbourFieldName  T;
            K                   K;
            value               uniform 300;
        }
