For manufacturers large and small, computational fluid dynamics (CFD) is a critical part of their workflows. Engineers use CFD techniques to solve diverse problems ranging from modeling the aerodynamic performance of vehicles, to reducing noise from HVAC systems, to simulating oil flow in a gearbox, and more.
In vehicle design, optimization is critical. Manufacturers compete not only on the aesthetics of a design but also on its efficiency. Aerodynamicists need to predict drag for various body designs versus baseline cases, modeling airflow over a surface to maximize fuel efficiency or enhance the range of electric vehicles (EVs). They also need to conduct aero-acoustic simulations to minimize vehicle cabin noise inside the vehicle. They must develop “styling that sells” while meeting tight project deadlines and satisfying targets and constraints related to other CAE disciplines such as crash, noise, and cooling.
