Nguyen,

Thank you for your reply. As you can read above, I was able to get the solution to converge, so my Cd plot now is fully converged (I don't have a picture to upload here at the moment, I...

Hi all,

I am simulating low speed flow over a 2D airfoil NACA 0012 in FLUENT. I can't get my simulation to converge.

My residuals plot and lift plot continue to diverge even after 10,000...
