Hello,

I run the 3d airfoil simulation at low re (1.5e5), high angle of attack (18 degree). However, these simulations is not converge both in residual and monitor data (cl). But when i run at a low angle of attack (0 degree) it is very easy to get convergence. So how do I get the data in this condition? btw i use k-o SST turbulence

Thanks
