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