Detailed Description

Computes the ensemble- or time-based singular-value average values, with optional windowing, from the output of function objects that generate non-field type values (e.g. Cd of forceCoeffs or momentum_x in momentum function objects).

Operands:

Operand Type Location
input - -
output file dat $FOAM_CASE/postProcessing/<FO>/<time>/<file>
output field - -
Usage
Minimal example by using system/controlDict.functions:
valueAverage1
{
    // Mandatory entries (unmodifiable)
    type              valueAverage;
    libs              (fieldFunctionObjects);

    // Mandatory entries (runtime modifiable)
    functionObject    <FO>;                       // forceCoeffs1;
    fields            (<field1> ... <fieldN>);    // (Cm Cd Cl);

    // Optional entries (runtime modifiable)
    resetOnRestart    false;
    window            0.5;

    // Optional (inherited) entries
    ...
}

where the entries mean:

Property Description Type Req'd Dflt
type Type name: valueAverage word yes -
libs Library name: fieldFunctionObjects word yes -
functionObject Name of function object to retrieve data word yes -
fields Names of operand fields wordList yes -
resetOnRestart Reset the averaging on restart bool no false
window Averaging window scalar no VGREAT

The inherited entries are elaborated in:

Usage by the postProcess utility is not available.
