Class
    Foam::functionObjects::writeCellVolumes

Group
    grpFieldFunctionObjects

Description
    Writes the cell-volumes \c volScalarField.

    Operands:
    \table
      Operand        | Type           | Location
      input          | -              | -
      output file    | -              | -
      output field   | volScalarField | $FOAM_CASE/<time>/V
    \endtable

Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    writeCellVolumes
    {
        // Mandatory entries (unmodifiable)
        type        writeCellVolumes;
        libs        (fieldFunctionObjects);

        // Optional (inherited) entries
        ...
    }
    \endverbatim

    where the entries mean:
    \table
      Property   | Description                        | Type | Req'd | Dflt
      type       | Type name: writeCellVolumes        | word |  yes  | -
      libs       | Library name: fieldFunctionObjects | word |  yes  | -
    \endtable

    The inherited entries are elaborated in:
     - \link functionObject.H \endlink

    Minimal example by using the \c postProcess utility:
    \verbatim
        postProcess -func writeCellVolumes
    \endverbatim
