Hi,
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. M.S. |

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.
