Class
    Foam::binModels::uniformBin
 
Description
    Calculates binned data in multiple segments according to
    a specified Cartesian or cylindrical coordinate system.
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    binField1
    {
        // Other binField entries
        ...
 
        // Mandatory entries
        binModel          uniformBin;
 
        binData
        {
            // Mandatory entries
            nBin          <Vector<label>>;
 
            // Optional entries
            cumulative    <bool>;
            minMax
            {
                e1        (<scalar> <scalar>); // (min max);
                e2        (<scalar> <scalar>);
                e3        (<scalar> <scalar>);
            }
        }
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                           | Type   | Reqd | Deflt
      binModel  | Type name: uniformBin                 | word   | yes  | -
      binData   | Entries of the chosen bin model       | dict   | yes  | -
      nBin      | Numbers of bins in specified directions | Vector<label> <!--
                -->                                              | yes  | -
      cumulative | Flag to bin data accumulated with increasing distance   <!--
                --> in binning direction                | bool   | no   | false
      minMax     | Min-max bounds in binning directions with respect to    <!--
                --> the coordinateSystem's origin       | dict   | no   | -
    \endtable
 
Note
  - The order of bin numbering is (e1, e2, e3), where the first
    varies the fastest. For example, for a cylindrical bin with
    \f$ nBin = (radial, azimuth, height) = (2, 4, 2) \f$, the bin indices
    may look like as follows - note the counterclockwise increments:
