CFD
CFD (Computational Fluid Dynamics) is a computer-based method used in aerospace and engineering to simulate how air, liquids, or gases flow around objects like aircraft, cars, or buildings. Think of it as a virtual wind tunnel where engineers can test designs on computers before building physical models. This saves companies time and money compared to traditional testing methods. When you see CFD mentioned in a resume, it means the candidate has experience using specialized software to analyze and improve designs. Similar terms you might see are "flow analysis," "aerodynamic simulation," or "fluid flow modeling."

Example Interview Questions
Senior Level Questions
Q: How do you validate CFD results and ensure their reliability?
Expected Answer: A strong answer should mention comparing simulation results with real-world testing data, using multiple analysis methods to cross-check results, and understanding the limitations of different simulation approaches.
Q: Tell me about a complex CFD project you managed and any challenges you overcame.
Expected Answer: Look for candidates who can describe leading teams, making strategic decisions about simulation approaches, and solving technical problems while meeting project deadlines and budget constraints.
Mid Level Questions
Q: What factors do you consider when setting up a CFD simulation?
Expected Answer: Should discuss choosing appropriate models for the problem, setting boundary conditions, and determining the right balance between accuracy and computational time.
Q: Describe a time when you had to optimize a design using CFD.
Expected Answer: Should explain how they used simulation results to improve a design, showing practical application of CFD tools and understanding of design constraints.
Junior Level Questions
Q: What CFD software have you used and what types of problems have you solved with it?
Expected Answer: Should be able to name common CFD software packages and describe basic analyses they've performed, such as simple flow problems or basic aerodynamic studies.
Q: Can you explain what mesh quality means in CFD?
Expected Answer: Should demonstrate basic understanding of how the simulation space is divided into smaller parts for analysis and why this is important for accurate results.
