yes, this is a solid body as we can see which is wrong as a wing should consist of shells/surfaces (skin and internal structure, e.g., ribs, etc).

You would need to have a collection of surfaces from your CAD and then it should come in as surfaces, which we can be surface mesh.

As the CAD you use is not an Ansys product, we can not advice on that.

But ultimately we need surfaces not solid/volumes like what you have now.

Thank you Erik
