Class
    Foam::fa::contactHeatFluxSource
 
Group
    grpFaOptionsSources
 
Description
    Applies contact heat flux between specified \c faMesh
    and \c fvMesh within a specified region for compressible flows.
 
Usage
    Minimal example by using \c constant/faOptions:
    \verbatim
    contactHeatFluxSource1
    {
        // Mandatory entries (unmodifiable)
        type                contactHeatFluxSource;
        Tprimary            <TprimaryFieldName>;
 
        // Optional entries (runtime modifiable)
        T                   <Tname>;
        thicknessLayers     (<layer1> <layer2> ... <layerN>);
 
        // Conditional optional entries (runtime modifiable)
 
            // when the entry "thicknessLayers" is present
            kappaLayers     (<layer1> <layer2> ... <layerN>);
 
        // Mandatory/Optional (inherited) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                       | Type  | Reqd | Dflt
      type      | Type name: contactHeatFluxSource  | word  | yes  | -
      Tprimary  | Name of primary temperature field | word  | yes  | -
      T         | Name of operand temperature field | word  | no   | T
      thicknessLayers | List of thicknesses of layers | scalarList | no | -
      kappaLayers | List of conductivities of layers | scalarList | cndtnl | -
    \endtable
 
    The inherited entries are elaborated in:
     - \link faOption.H \endlink
     - \link faceSetOption.H \endlink
     - \link temperatureCoupledBase.H \endlink
