Formula Student - Sidebox CFD Simulation - cleaning CAD

Hi Stephan,

I’m not quite sure what you want to achieve in your first problem. If I have to guess, I will suggest using porous media in order to simulate the radiator. You can then use the front and aft surface of the radiator to get velocity and pressure distributions in order to compare your two configurations.

As for your second concern; self-intersecting surfaces should not be an issue for snappyHexMesh; but you can use the boolean operations in your CAD software to get the union of flap and sidebox. If you have duplicate faces, you should get rid of them.

If you find any issues during meshing of your simulation, chances are they have been addressed in the many replies to this post.
