Class
    Foam::CourantNo
 
Group
    grpUtilitiesFunctionObjects
 
Description
    This function object calculates and outputs the Courant number as a
    volScalarField.  The field is stored on the mesh database so that it can
    be retrieved and used for other applications.
 
    Example of function object specification to calculate the Courant number:
    \verbatim
    CourantNo1
    {
        type        CourantNo;
        functionObjectLibs ("libutilityFunctionObjects.so");
        ...
    }
    \endverbatim
 
    \heading Function object usage
    \table
        Property     | Description             | Required    | Default value
        type         | Type name: CourantNo    | yes         |
        rhoName      | Name of density field   | no          | rho
        phiName      | Name of flux field      | no          | phi
        resultName   | Name of Courant number field | no     | <function name>
        log          | Log to standard output  | no          | yes
    \endtable
