Using a 2022 F1 car model, I am finding difficulties with having a solid body and creating a valid enclosure. The model was a .stl file that is a faceted body within Ansys. As shown in the first image, I made an enclosure perfectly fine with no issues with this faceted model. But,

Can I use this faceted model and enclosure for Ansys Fluent simulations or do I have to convert it to a solid to make the mesh?

I tried to convert it to a solid and it worked, but when I made an enclosure for it, SpaceClaim was unable to subtract the body from the enclosure, resulting in an error I do not know how to fix in the 2nd picture. Any help would be greatly appreciated, thanks!

When you convert the car into a solid, can you do a geometry check to verify that it is free of errors? Right click on the solid in your structure tree and select Check Geometry.

I have tried this but it crashes every time I perform it, would a facet body work? That would be way simpler for my purposes.

This tells me that your faceted geometry is not clean.

You can still try to proceed with the mesh. If not with the Watertight Geometry workflow in Fluent Meshing, with the Fault Tolerant Meshing workflow.
