So I have been having some issues with orthogonal quality while trying to mesh an airfoil close to the ground. I am running this simulation for FSAE so I need to account for ground effect. With a regular simulation I get a OQ around .2-.3 however the moment I add the ground my OQ shoots down to about .003 which is very poor.

ANSYS tells me that I should use "Inverse Orthogonal Quality in Fluent Meshing", however I can not find this anywhere.

So, how can I change to IOQ or how else can I improve my mesh.

P.S. I am having troubles getting a quality mesh that accounts for ground effect. I currently just have a box with the airfoil close to the ground and then I used edge sizing to make it finer near the ground and airfoil. Is there another design style I can use?

Thank you very much in advance for any help and remember, I am a student.
