Hi everyone,

I am running turbFOAM with a k-e turbulence model and wanted to see the evolutions of the Reynolds stresses during the calculation.
So I was looking for a way to write a R file for each step next to U, k, epsilon, etc... But I'm a bit lost and don't know where to start.
Where is the part of code stipulating which output has to be written down?

Thank you in advance

Laurent

Default mkDir(runTime.path()/"xyz");

mkDir(runTime.path()/"xyz");

OFstream logFile(runTime.path()/"xyz"/"myLog.dat");

logFile << bla bla bla << endl;

Reynolds stress never gets calculated, it there is no option to write it out.

The divergence or R does get calculated, but it is a temporary field and does not exist for most of the calculation.



If you want to write out R, you first have to create the R field in createFields after the turbulence model has been constructed:

volVectorField R
(
IOobject
(
"R",
runTime.timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
turbulence().R()()
);

Then you have to update it after each loop:
R = turbulence().R()();

calculate it using the turbulence().R()() function call.

It will write out automatically.

thanks very much for your messages. It now works after some minor tuning.
