Class
    Foam::regionFaModels::thermalShell
 
Description
    Thermal-shell finite-area model. It solves the energy
    equation in 2D. The coupling with the 3D region is done through
    the \c temperatureCoupledBase, plus \c faOption is available to
    add extra sources on the shell such as \c externalHeatFluxSource etc.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory/Optional (inherited) entries
        ...
 
        // Mandatory entries (unmodifiable)
        thermalShellModel   thermalShell;
        thermo
        {
            // subdictionary entries
        }
 
        // Mandatory/Optional (derived) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property   | Description                      | Type  | Reqd | Dflt
      thermalShellModel | Type name: thermalShell   | word  | yes  | -
      thermo     | Solid thermal properties         | dictionary | yes | -
    \endtable
 
    The inherited entries are elaborated in:
      - \link thermalShellModel.H \endlink
