I am trying to simulate the effects of ground effect in ANSYS on a GEV. So far I have only attempted to simulate an airfoil, however, the Cd values that I'm getting are much higher than what I've found out to be accurate with research although my Cl values are accurate. Please find attached my set-up for the geometry and mesh as well as my results for Cd as well as the paper i am comparing it to. if you have any questions then please ask.
