I get this error, but when I want to see the body in particular, it doesn't show anything but a plus mark.
Is there anyone out there who can help me solve this problem? I tried many things, including simply surpressing the body. Then the mesh will get a green check, but after that I can't move to the next step.

What geometries are you dealing with? Are you able to visualize them in SpaceClaim? post a snapshot of what you are dealing with? Also, try renaming the parts in the CAD program?

Can you provide a snapshot of what you have in the details of Mesh?

You say, "I'm trying to mesh this wing in CFX for aerodynamics."
I only see sheet bodies in your 3D domain. The mesher is expecting at least one solid body, which would represent the air around the wing.
Have you considered, or already done, a 2D model of that wing? If you are new to CFD, I would recommend you start with a 2D model. That means you construct a surface that represents a region of air around the wing, and the wing is a cutout near the center of that surface. Here is a tutorial.

You have to suppress all the surface bodies and have just one solid body.
I recommend you first do a 2D simulation of the airflow around that wing profile.

I will try to do the 2D simulation first.
For the 3D simulation, how do I create solids?

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.

Do you know where I can find the command Sew?
