I am using openFOAM v2312 and I am trying to do fieldAveraging of U p and T in my case file.

I have implemented the fieldAverage as per the openFOAM documentation but it is not working. After running the case I do not find any averaged files written.
I am a beginner in this software, so any help is appreciated. I am posting the controlDict file below, where I have implemented the fieldAverage

Also is there a way to do fieldAverage as a postProcess. I don't see fieldAverage as an option in postProcess -list.
Thanks.

{
version 2.0;
format ascii;
class dictionary;
object controlDict;
}

application rhoCentralFoam;

startFrom startTime;

startTime 0;

fieldAverage1
{

libs (fieldFunctionObjects);
writeControl writeTime;

fields
(
U
{
mean yes;
prime2Mean no;
base time;
}

p
{
mean yes;
prime2Mean no;
base time;
}

T
{
mean yes;
prime2Mean no;
base time;
}

);

}

Hello,

Do you see info related to this function object in your terminal/log file when running the solver? (look for the solver start up and on write times)

Do you see files such as UMean, pMean, TMean in your time step directories?

Hello,

Thanks for the reply.

There is no information about the fieldAverage when I run it. Even at write times, it just shows the usual residual Ux, Uy etc. It does not display anything indicating as if averaging is happening. The time step directories have a folder called uniform. Uniform contains, functionObjects folder and a time file. The functionObjects folder has a functionObjectProperties file, which is just empty. I will post the functionObjectProperties file below.

The time file just indicates at which time it is getting written.

FoamFile
{
version 2.0;
format ascii;
arch "LSB;label=32;scalar=64";
class dictionary;
location "0.1/uniform/functionObjects";
object functionObjectProperties;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

Alright, I misread your controlDict.

You are missing the functions{} section to encapsulate your function object definition:

functions
{
	fieldAverage1
	{
		type fieldAverage;
		libs (fieldFunctionObjects);
		writeControl writeTime;

		fields
		(
			U
			{
				mean yes;
				prime2Mean no;
				base time;
			}

			p
			{
				mean yes;
				prime2Mean no;
				base time;
			}

			T
			{
				mean yes;
				prime2Mean no;
				base time;
			}

		);

	}
}

Let me know if it solved the problem.
