I want to calculate a turbulent flow with the solver turbFoam. Since this solver is also used in one of the tutorials from the users guide I looked at this case. In the "0" folder of the case, there are, besides pressure and velocity, two variables defined , called "nuTilda" and "R". Does anyone know which physical properties are represented by these variables?
Thank you!

Dear Sven,

R is the Reynolds Stress and nuTilda is the effective viscosity in Spalart-Almaras-model. Both are not used if you run k-e, but they are there because turbFoam would fall over if you switch to say SpalartAllmaras.

You can find out by browsing in
