Class
    Foam::uniformFixedMultiphaseHeatFluxFvPatchScalarField
 
Description
    Uniform fixed heat flux boundary condition for Eulerian multi-phase cases.
    Constructs a mixed constraint which portions the heat flux between the
    phases in such a way as to keep the boundary temperature uniform across all
    phases. The heat flux can be specified as a time-varying function, and an
    under-relaxation factor can be supplied if this is necessary to maintain
    stability.
 
Usage
    \table
        Property     | Description                | Required | Default value
        q            | Heat flux [w/m^2]          | yes      |
        relax        | Relaxation factor          | no       | 1
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            uniformFixedMultiphaseHeatFlux;
        q               1000;
        relax           0.3;
        value           $internalField;
    }
    \endverbatim
