Fan Noise Simulation Using HELYX

Automotive cooling fans are one of the major noise sources within a vehicle and can generate 85dBA at certain frequencies. That’s as loud as a lawn mower or a screaming child. Extended periods above 85dBA can lead to permanent hearing loss. With the average American spending 8.5 hours driving per week, reducing fan noise is […]

Power in Numbers: Assessing Vehicle Convoy Aerodynamics with CFD Simulation

While the idea of autonomous driving has been around for many decades, recent advances in software, computational power, sensors and mobile communication techniques have accelerated the development and understanding. Already, drive assistance systems, such as lane holding, cruise control and emergency braking have made it into production cars, making a ride in a vehicle more […]

Introduction to Meshing with HELYX

Creating a computational mesh is an extremely important step in the overall process of CFD analysis. A “bad” mesh leads to solver instability; poor resolution of important flow features; poor parallel performance of your solver; and in general, inadequate and inefficient use of CFD as a design tool. A “great” mesh enables your CFD solvers […]
