Pressure gradient

I'm running airfoil simulations and noticing that I'm not getting enough pressure gradient on the foil surface - thus weak/delayed stall + lower than expected drag on some cases. I'm running k-wSST at Re = 1e5.

Any good ideas or know parameters I can tinker with to solve the problem?

Thank you.

I would take a close look at your boundary layer mesh (overall thickness and y+ specifically) and see how it compares to published work of similar problems (lots of stuff out there).

Hope this helps.
