FEA
FEA (Finite Element Analysis) is a computer-based method that engineers use to test and predict how products will perform in the real world without having to build physical prototypes. Think of it as a virtual testing ground where engineers can simulate how parts might bend, break, heat up, or vibrate under different conditions. This saves companies time and money compared to building and testing actual physical models. You might also see it referred to as "finite element method" or "FEM." It's widely used in aerospace for testing aircraft parts, spacecraft components, and other complex structures before they're manufactured.

Example Interview Questions
Senior Level Questions
Q: How do you validate FEA results and ensure their accuracy?
Expected Answer: A strong answer should mention comparing results with physical tests when possible, checking mesh quality, performing convergence studies, and validating assumptions. They should emphasize the importance of real-world experience in interpreting results.
Q: Describe a complex analysis project you've led and how you handled challenges.
Expected Answer: Look for answers that demonstrate project management skills, technical leadership, and ability to solve complex problems while meeting deadlines and working with multiple stakeholders.
Mid Level Questions
Q: What factors do you consider when setting up an FEA model?
Expected Answer: Should discuss material properties, boundary conditions, loading conditions, and mesh quality in simple terms. Should show understanding of balancing accuracy with computational efficiency.
Q: How do you determine if your analysis results are reasonable?
Expected Answer: Should mention checking against hand calculations, comparing with similar past projects, and using engineering judgment to verify results make sense.
Junior Level Questions
Q: What FEA software have you used and what types of analysis have you performed?
Expected Answer: Should be able to name common FEA software packages and describe basic analyses like stress analysis or thermal analysis. Understanding of basic concepts is more important than specific software experience.
Q: Explain what mesh quality means in FEA.
Expected Answer: Should be able to explain in simple terms how breaking down a model into smaller pieces (mesh) affects analysis accuracy, and basic concepts of good versus poor mesh quality.
