Hello all,

I am trying to run multiple simulations of a supercritical aerofoil with a high velocity jet at trailing edge using the SA turbulence model. So far I have managed to obtain mesh independence even if I maintained a y+ value of between 15 - 35. I know the y+ is important for SA and it should be kept as close as possible to 1 but when I try to do so, my simulations diverge and crash.

I am using ICEM to generate a C grid structured mesh with boundaries at 25 chords away. All simulations are done at low Mach (0.1), chord of 1m and jet velocities between Mach 0.2 -0.4.

Anyone who has encountered this issue before or knows how to solve it?
