Convergence for NACA 0012 tutorial example?

GDS · July 26, 2021, 17:08

I tried running the incompressible NACA 0012 tutorial example, but I killed SU2 after about 24 hours and over 10,000 steps. The Cl and Cd were pretty much constant, but p and nu were still changing. How many iterations should it take? I ran this same example in OpenFOAM, and it only took 2 - 3 hours and 1367 steps to converge (and got accurate results).

Hi... That is not a very good way to ask questions...
