We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

For a 3D Model, if your wing parts are solid bodies, then in DesignModeler, you create an Enclosure. This is a solid that is the box of air around the wing, with the wing solids subtracted to make a cavity in the air.  You then suppress the wing parts and are left with one solid that represents the air with a cavity where the wing used to be. All surfaces of a solid are considered walls in Fluent, so you just name one end of the box inlet and the other end of the box outlet and you will have created a wind tunnel with a wing in it.


I'm not sure your wing parts are solids, they may just be surfaces. There is a command called Sew that can sew together all the surfaces and make a solid, as long as the surfaces define an airtight volume.
