Decent 3d models for CFD

[christian.falavena]

Hi all, I’m trying to do a CFD sim for an F1 floor. The main problem is that every solid model on the web has straight strakes and not turning on outside, so it’s a completely messed up design.
I found a decent model but it was only in STL format, so impossible to do a CFD with.
If anyone has some decent car models please suggest or help me. Thank you very much

You can ask MVRC crowd to donate their year old car. Doubt you will find anything good in internet otherwise

In MVRC we only use .stl for the geometry. So it's not impossible . SnappyHexMesh happily accepts stls as input.

the .stl file is only for geometry and to create a mesh so maybe you can do it in simflow 4.0

Can't you save the STL into a different format that you can use? I use Solidworks and you can save nearly anything as nearly anything else.

Yeah but when I try to simulate it, it results as a zero thickness surface, and with every 3D tool it’s impossible to thicken it because it’s a complex model

The issue is that it's modelled as a surface with no thickness rather than it being an STL then

Is there a way to solve this?

Ansa would be your friend to do the geometry clean-up.
