Hello,

I am doing a validation of the ANSYS AIM software, mainly flow analysis. I started with a simple airfoil analysis (infinite wing). AIM automatically turns off the 'intermittency re theta' option in Physics Options, this makes the boundary layer fully turbulent (?). To get a transitional boundary layer (because the drag was way to high), I turned on this model. Convergence is way harder now with this model on, see picture in attachment. Does someone know a solution to this problem? Thanks in advance.
