Car model for school project - Cant convert from Surface to solid
You STL Mesh contains may to many facets for Fusion 360 to convert to a Brep in its current state.

Hi @rasmc19,
@jhackney1972 was earlier with his response 😉
What you can try is using Meshmixer to optimize the mesh model so you can try to convert it to BRep as @jhackney1972 said.
Hier, you can download Meshmixer

This isn't a surface model. It is a triangulated mesh, the least common denominator of any forms of 3D geometry representation. It has over 600000k polygons.
The current limit for Fusion 360 to convert this into a solid model, or surface model I believe is 20,000 polygons.
If you decimate the mesh either in Meshmixer or in Fusion. 360 from 600,000+ polygons to under 20,000 polygons you'll likely lose so much detail that that model is going to b totally useless for CFT as it will be very faceted.
CFD software usually works with BRep and/or NURBS surfaces. Those are mathematically precise descriptions of 3D geometry and they are free of resolution. While CFD and FEA software might use their own meshing algorithms, the structure of those meshes is very different from that of a .stl mesh used for 3D printing.
