Class
    Foam::functionObjects::binField

Group
    grpFieldFunctionObjects

Description
    Calculates binned data, where specified patches are divided into
    segments according to various input bin characteristics, so that
    spatially-localised information can be output for each segment.

    Operands:
    \table
      Operand      | Type                          | Location
      input        | vol<Type>Field(s)          <!--
               --> | <time>/<inpField>s
      output file  | dat                           <!--
               --> | postProcessing/<FO>/<time>/<file>
      output field | -                             | -
    \endtable

    where \c <Type>=Scalar/Vector/SphericalTensor/SymmTensor/Tensor.

Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    binField1
    {
        // Mandatory entries
        type                    binField;
        libs                    (fieldFunctionObjects);
        binModel                <word>;
        fields                  (<wordHashSet>);
        patches                 (<wordRes>);
        binData
        {
            // Entries of the chosen binModel
        }

        // Optional entries
        cellZones               (<wordRes>);
        decomposePatchValues    <bool>;

        // Conditional optional entries

            // General coordinate system specification
            coordinateSystem
            {
                type        cartesian;
                origin      (0 0 0);
                rotation
                {
                    type        ...
                    ...
                }
            }

            // Define the centre of rotation
            // with implicit directions e1=(1 0 0) and e3=(0 0 1)
            CofR            (0 0 0);

        // Inherited entries
        ...
    }
    \endverbatim

    where the entries mean:
    \table
      Property  | Description                           | Type   | Reqd | Deflt
      type      | Type name: binField                   | word   | yes  | -
      libs      | Library name: fieldFunctionObjects    | word   | yes  | -
      binModel  | Name of the bin model                 | word   | yes  | -
      fields    | Names of operand fields           | wordHasSet | yes  | -
      patches   | Names of operand patches             | wordRes | yes  | -
      binData   | Entries of the chosen bin model       | dict   | yes  | -
      decomposePatchValues | Flag to output normal and tangential      <!--
                --> components                          | bool   | no   | false
      cellZones | Names of operand cell zones          | wordRes | no   | -
      coordinateSystem | Coordinate system specifier    | dict | cndtnl | -
      CofR    | Centre of rotation                      | vector | cndtnl | -
    \endtable

    Options for the \c binModel entry:
    \verbatim
      singleDirectionUniformBin    | Segments in a single direction
      uniformBin                   | Segments in multiple directions
    \endverbatim

    The inherited entries are elaborated in:
      - \link fvMeshFunctionObject.H \endlink
      - \link writeFile.H \endlink
      - \link coordinateSystem.H \endlink

Note
  - If a \c coordinateSystem entry exists, it is taken in favour of \c CofR.
