Class
    Foam::functionObjects::PecletNo
 
Group
    grpFieldFunctionObjects
 
Description
    Computes the Peclet number as a \c surfaceScalarField.
 
    Operands:
    \table
      Operand        | Type               | Location
      input          | surfaceScalarField | <time>/inputField
      output file    | -                  | -
      output field   | surfaceScalarField | <time>/outputField
    \endtable
 
Usage
    Minimal example by using \c system/controlDict.functions:
    \verbatim
    PecletNoFO
    {
        // Mandatory entries
        type            PecletNo;
        libs            (fieldFunctionObjects);
 
        // Optional entries
        rho             <word>;
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                        | Type | Reqd  | Deflt
      type         | Type name: PecletNo                | word |  yes  | -
      libs         | Library name: fieldFunctionObjects | word |  yes  | -
      rho          | Name of density field              | word |  no   | rho
    \endtable
 
    The inherited entries are elaborated in:
