Hello everyone,


I'm trying to validate a well-known case, turbulent flow over NACA0012. Information of the validation ca be found here: https://turbmodels.larc.nasa.gov/naca0012_val.html

I simulated properly the case with the version of OpenFoam v2006, obtaining succefull results. I can say that I validated the case because I got accuracy values for Cl and Cd for differents angles of attacks (0, 3, 6, 9, 12 and 15). I did that with two different turbulence models (RAS-Spalart Allmaras and RAS-KwSST) using the solver simpleFoam.

The problem is the following one. I tried to run the SAME case with a version of OpenFoam installed by means of Docker. (IN THE SAME LAPTOP).

Both are supposed to be the same version but the results are differents (Relative error 30 %) and it isn't related with the time of convergence.

Has anyone suspect where can be the problem?

If someone is interested in look over the code, the case for AoA 3 degrees is here:
https://drive.google.com/file/d/1p2P...ew?usp=sharing

The case is ready to run with simpleFoam.

Thank for your time.

Make sure mesh and solver setting are equal.

Thank you very much for the reply.

They are the same file. (Copy and paste)
That’s the crazy thing.

I'm sure it is related with the solver.
Where I can find the defualt values that OF uses?
I'm searching in the libraries, but I didn't find anything which could fix it
