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
 
            // Option-1, i.e. general coordinate system specification
            coordinateSystem
            {
                type            cartesian;
                origin          (0 0 0);
                rotation
                {
                    type        axes;
                    e3          (0 0 1);
                    e1          (1 0 0); // (e1, e2) or (e2, e3) or (e3, e1)
                }
            }
 
            // Option-2, i.e. the centre of rotation
            // by inherently using e3=(0 0 1) and e1=(1 0 0)
            CofR                (0 0 0);
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table

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