Class
    Foam::functionObjects::fluxSummary
 
Group
    grpFieldFunctionObjects
 
Description
    Computes the volumetric- or mass-flux information across selections of face
    zones.
 
    Operands:
    \table
      Operand       | Type | Location
      input         | -    | -
      output file   | dat  | postProcessing/<FO>/<time>/faceName
      output field  | -    | -
    \endtable
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    fluxSummaryFO
    {
        // Mandatory entries
        type            fluxSummary;
        libs            (fieldFunctionObjects);
        mode            <word>;
 
        // Optional entries
        phi             <word>;
        scaleFactor     <scalar>;
        tolerance       <scalar>;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                        | Type | Reqd  | Deflt
      type         | Type name: fluxSummary             | word |  yes  | -
      libs         | Library name: fieldFunctionObjects | word |  yes  | -
      mode         | Mode to generate faces to test     | word |  yes  | -
      phi          | Name of surface flux field         | word |  no   | phi
      scaleFactor | Factor to scale results             | scalar | no  | 1.0
      tolerance   | Tolerance for reference direction   | scalar | no  | 0.8
    \endtable
 
    The inherited entries are elaborated in:
     - \link functionObject.H \endlink
     - \link writeFile.H \endlink
 
    Options for the \c mode entry:
    \verbatim
      faceZone
      faceZoneAndDirection
      cellZoneAndDirection
      surface
      surfaceAndDirection
    \endverbatim
 
Note
    For surface and direction, phi='U' can be used for determining the fluxes.
