Hi, every OpenFoamer

In the controlDict file of my DNS case, there are the following codes to calculate the average:


functions
{
fieldAverage1
{
type fieldAverage;
functionObjectLibs ( "libfieldFunctionObjects.so" );
enabled true;
outputControl outputTime;

fields
(
U
{
mean on;
prime2Mean on;
base time;
}

p
{
mean on;
prime2Mean on;
base time;
}
);
}
}


What confused me is that how to calculate average in the source codes.I mean in the source codes, we should take a long time to eliminate the influence of average even if the flow field was already convergence.

Thank you!!1
