Class
    Foam::functionObjects::processorField
 
Group
    grpFieldFunctionObjects
 
Description
    Writes a scalar field whose value is the local processor ID.  The output
    field name is \c processorID.
 
    Operands:
    \table
      Operand        | Type           | Location
      input          | volScalarField | $FOAM_CASE/<time>/<inpField>
      output file    | -              | -
      output field   | volScalarField | $FOAM_CASE/<time>/<outField>
    \endtable
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    processorField1
    {
        // Mandatory entries (unmodifiable)
        type        processorField;
        libs        (fieldFunctionObjects);
 
        // Optional (inherited) entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                        | Type | Req'd | Dflt
      type         | Type name: processorField          | 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 processorField
    \endverbatim
