    How do I use FEA and Flow Simulation correctly?

    Jimmy Tran

      So, I've used Inventor for simple stuff for making quick prototypes but I never used FEA and Flow Simulation in my 4 years of high school. I'm finally in college and I've finally finished my Freshman CAD class which uses Solidworks. The last thing we learned was FEA and Flow Simulation, kinda. What we did is they gave us files that were already there, but we just had to run the simulation. At the end of the lesson he said that we haven't taught you everything you need to know to effectively use Flow Simulation and FEA which can both give false data that looks right. So what I was wondering is how do you get accurate readings from these simulations? How would you get correct data outputs?

       

      One of the main reasons why I want to learn this is because I'd like to learn how to make a simple aircraft body. So how would I find the lift of a wing section and how would I find if the plane would be stable?

          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.
