I'm trying to perform an air flow simulation on a part that I imported. I used the import doctor to try to fix the geometry and create a solid. But running the simulation, I think it isn't actually doing anything. It appears as a solid body that's why I thought it would work but apparently no.
Define appears as a solid body? How did you test for solid geometry? You may not have solid geometry in the model. Shaded surfaces can appear solid so seeing a shaded image is not confirmation of solid geometry existence in a model.
If you view the import in wireframe you can tell immediately if it is a solid or not based on your system color assignments.
