The Challenge in Automotive Aerodynamics
High-resolution 3D datasets for automotive aerodynamics are scarce, making it hard to create efficient machine learning (ML) models. Most available resources are low quality, restricting improvements in aerodynamic design. Addressing these gaps is essential for enhancing predictive tools and speeding up vehicle design.
Limitations of Current Aerodynamic Data
Traditional aerodynamic data generation methods use low-resolution or simplified geometries, failing to meet the demands of high-performance ML models. For instance, the AhmedML dataset has only about 20 million cells, far below the industry standard of over 100 million. This reduces the practicality of ML models for real-world applications. Moreover, existing datasets lack geometric diversity and accurate simulation techniques, which limits their utility in addressing complex aerodynamic challenges.
Introducing WindsorML
WindsorML, developed by researchers from Amazon Web Services, Volcano Platforms Inc., Siemens Energy, and Loughborough University, overcomes these challenges. This high-quality, open-source CFD dataset includes 355 geometric variations of a typical vehicle body, providing excellent detail with over 280 million cells.
