Dear Foamers,

Recently, I want to obtain the field average of a specific field (e.g., U and p). This can be achieved through the functionality of 'fieldAverage1' in the 'ControlDict'.
To discard the startup effect, the simulation data of previous 5s should be discarded for the averaging operation in my case.

How can I achieve this specific feature?

functions
{
	fieldAverage1
	{
		type                fieldAverage;
		libs                ("libfieldFunctionObjects.so");

		writeControl    writeTime;

		restartOnRestart    false;
		restartOnOutput     false;
		periodicRestart     false;
		restartPeriod       0.002;	

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

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

Any comments are highly appreciated!
Thanks.

Any functionObject can be started using timeStart and ended by timeEnd:

timeStart           5;
timeEnd             10;
