Default Problems with Convergence

I'm having problems with convergence..I use a mesh with a Y+ of 0.65 before the implementation of the SST turbulence transition model...

Then i use the transition model on the same mesh but the problem don't converge...any ideas?

thanks in advance,

Before using the SST model which model did you use. Y+ of 0.65 seems to be too fine. Reduce it around 2-4 for SST. Could you also provide more details about your simulation as Y+ value may not be the problem for the non-convergence.

Thanks Luke,

I'm analizing a NACA4415 and NACA4418 to choose the best one of them...the data are:
