Class
    Foam::fv::tabulatedHeatTransfer
 
Group
    grpFvOptionsSources
 
Description
    Applies a tabulated heat transfer model for inter-region heat exchanges.
 
    The 2D table returns the heat transfer coefficient
    by querying the local and neighbour region velocities.
 
    Required fields:
    \verbatim
      AoV       | Area per unit volume of heat exchanger    [1/m]
    \endverbatim
 
Usage
    Minimal example by using \c constant/fvOptions:
    \verbatim
    tabulatedHeatTransfer1
    {
        // Mandatory entries (unmodifiable)
        type            tabulatedHeatTransfer;
        outOfBounds     clamp;
        file            "table";
 
        // Optional entries (unmodifiable)
        U               <Uname>;
        UNbr            <UnbrName>;
 
        // Mandatory/Optional (inherited) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                      | Type  | Reqd | Dflt
      type      | Type name: tabulatedHeatTransfer | word  | yes  | -
      file  | Heat transfer coefficient table  | interpolate2DTable | yes | -
      U         | Name of operand velocity field   | word  | no   | U
      UNbr      | Name of operand neighbour velocity field | word | no | U
    \endtable
 
    The inherited entries are elaborated in:
     - \link interRegionHeatTransfer.H \endlink
     - \link interpolate2DTable.H \endlink
