Good day to all!

I'm a beginner to OpenFOAM. I'm using OpenFOAM 2.0.1 and now learning OpenFOAM with the dieselFoam tutorial. I'm trying to write the domain averaged data on an output text file but I couldn't get it out. Let's say for instance I try to extract the averaged pressure, I added

================================================== ===================
functions
(
pAverage
{
functionObjectLibs ("libutilityFunctionObjects.so");
type coded;
redirectType average;
outputControl outputTime;
code
#{
const volScalarField& p =
mesh().lookupObject<volScalarField>("p");
Info<<"p avg:" << average(p) << endl;
#};
}
);
================================================== ===================

into the controlDict file. It's supposed to at least write the average pressure to the terminal if I'm not mistaken but I didn't observe anything.

Can you please kindly advise that how can I solve the problem?

Thank you very much in advance.

Best regards,
Kar.

Problem is outputControl. The FO is only executed if the data is written. So there IS output. Just not as often as you'd like it
