ghost New Member Join Date: Sep 2009 Posts: 27 Rep Power: 17	hi i am running a 2D aerofoil simulation, with injection blowing at leading edge and the solution refuse to converge even after 200 000 iterations. there are large fluctuation in the residuals, and the lift n drag coefficient are too high. i ran over a few AoA, and there seem to be no stalling even at 20degrees. is there something wrong with my mesh? thank you.
