Convergence issues with NACA 0012 RANS Test Case
Hi,
I have been running the NACA 0012 RANS Test Case for different angles of attack for both the SST and SA turbulence models and with the 897x257 mesh available in the repository. With the SST model I have had no problems, but with SA for AoA>12 degrees the solution diverges after a few iterations. The only change I did in the configuration file was adding the WITHFT2 because the User's Guide recommends using it when using the NEGATIVE modification of the SA model. Does anyone know if there is something I could change in order for it to converge? Thanks in advance. |
Could you maybe show how well it does compared to the validation results from NASA:
https://turbmodels.larc.nasa.gov/naca0012_val.html They use a very fine grid, and they report results up to a=15 |
