Reynolds stress tool "R"
 

Hi,

I need some help with a postprocessing tool in OpenFoam.
The case is an incompressible turbulent channel flow at a low reynolds number and I use the LaunderSharma-ke-model.
By using the tool "R" I can calculate the Reynolds stresses for the current/the first timestep.
How can i calculate the Reynolds stresses for another timestep?

I already used "createTurbulenceFields", but the results cannot be correct..

regards insel
