Greetings @hugohugochung

The meshing log is complaining specifically about one interface

It’s this interface right here. You can see that the bodies are intersecting each other. Just repair it in your cad tool and try meshing again:

Also, I recall of a similar public project which you might be interested in… it will help you with the overall setup: https://www.simscale.com/projects/kristina/sneeze_4/

If you run into trouble, just let us know
