Class
    Foam::functionObjects::valueAverage
 
Group
    grpFieldFunctionObjects
 
Description
    This function object calculates the average value from the output of
    function objects that generate singular values.
 
Usage
    Example of function object specification:
    \verbatim
    valueAverage1
    {
        type        valueAverage;
        libs        ("libfieldFunctionObjects.so");
        ...
        writeToFile yes;
        log         yes;
        functionObject forceCoeffs1;
        fields      (Cm Cd Cl);
        window      0.5;
    }
    \endverbatim
 
    Where the entries comprise:
    \table
        Property     | Description             | Required    | Default value
        type         | type name: valueAverage | yes         |
        writeToFile  | write average data to file |  no      | yes
        log          | write average data to standard output | no | yes
        fields       | list of fields to process | yes       |
        functionObject | Name of function object to retrieve data from | yes |
        resetOnRestart | Reset the averaging on restart | no | no |
    \endtable
 
    Output data is written to the file <timeDir>/valueAverage.dat
