Class
    Foam::fixedMultiPhaseHeatFluxFvPatchScalarField
 
Description
    Calculates a wall temperature that produces the specified overall wall heat
    flux across all the phases in an Eulerian multi-phase simulation.
 
    Intended to be used with copiedFixedValue to ensure that phase wall
    temperature are consistent:
        - Set 'fixedMultiPhaseHeatFlux' boundary for one of the phases
        - Use 'copiedFixedValue' for all the other phases.
