I have a small question regarding convergence and I would be most grateful if any one can answer it.
I did a 2D problem earlier of a wing and it took the lift and drag about 8000 iterations to converge, however I modelled the similar wing in 3D and this time it the solver about 2500 iterations to converge on a solution.
My question is how come this happened even though I have used similar boundary conditions and turbulence model? Is 3D quick compared to 2D?
Any suggestions would be greatly appreciated.
Thanks in advance.
