How do engineers ensure that Computational Fluid Dynamics (CFD) simulations are accurate and reliable? The answer lies in Verification and Validation (V&V), two essential processes that guarantee the correctness and trustworthiness of CFD models. In this video, we break down the concepts of V&V in simple terms: Verification ensures that the equations are solved correctly by eliminating computational errors and numerical instabilities. Validation ensures that the results match real-world data, proving the model’s accuracy in practical applications. From verifying mesh refinement to validating simulations against wind tunnel data, these steps play a crucial role in industries like aerospace, civil engineering, and environmental design. Learn how V&V builds confidence in CFD models and why it’s critical for designing safer cities, efficient aircraft, and much more.
