By taking a class on the subject and doing considerable advanced study.
For example, in our college curriculum - that is third year (with statics foundation) and forth year (with dynamics foundation) topics.
Validate digital results with physical testing, then you can use your digital model for prediction (within educated limits) of results of design changes.
Good luck in college! If you are looking for a school....
you're in luck, the software has great tutorials and technical references, i would go through those first and set some expectations relative to your current education and the level of analysis you're trying to do. the guys at nasa work at nasa for a reason and there is also a reason they have wind tunnels and not just CFD. there are a lot of great discussions on the forum about what you're trying to do, follow those and go from there. I think look for josiah.
