SUZUKI Accelerates Validation of ‘RICOS Lightning’ to Streamline Aerodynamic Development

SUZUKI MOTOR CORPORATION (Headquarters: Hamamatsu, Shizuoka; Representative Director and President: Toshihiro Suzuki; hereinafter referred to as “SUZUKI”) is advancing the validation of ‘RICOS Lightning’ an AI-CAE solution provided by RICOS Co. Ltd. (Headquarters: Chiyoda, Tokyo; CEO: Yu Ihara; hereinafter “RICOS”). By leveraging RICOS’s proprietary AI-CAE algorithms, SUZUKI aims to significantly accelerate aerodynamic simulations in automotive design, establishing a more efficient design process.

Aerodynamic performance is a key factor for fuel efficiency and is heavily influenced by vehicle shape. As such, precise shaping in the digital phase, prior to physical manufacturing, is essential. While fluid simulations address this need, the challenge remains that each simulation pattern requires an extensive amount of computational time. To address this, SUZUKI has turned to AI-driven rapid predictions. However, conventional AI solutions have limitations when predicting outcomes with unseen data. ‘RICOS Lightning’ tackles this constraint by employing methods that enable both speed and reliability in prediction, even for new data. Using a licensed ‘RICOS Lightning’ system, SUZUKI is currently conducting validation on a variety of vehicle shapes, progressing toward full-scale implementation.

■RICOS original AI algorithm – ‘IsoGCN’
RICOS Lightning includes our original AI algorithm called ‘IsoGCN’, which can predict simulation outcomes both rapidly and with great accuracy. Designed specifically for use with simulation data, ‘IsoGCN’ features four key characteristics.

1. High speed: IsoGCN reduces computation significantly compared to traditional simulations, enabling faster simulations.
2. 3D Data Comprehension: It accurately understands 3D shapes, making it suitable for predicting complex product designs.
3. Extrapolation for Shapes: Incorporating methods like fluid, thermal, and structural analysis, IsoGCN delivers reliable results for new product shapes.
4. Easy Operation: It eliminates the need for rigorous meshing work required in traditional CAE simulations, speeding up the process and making it accessible to non-experts.
Using IsoGCN can reduce simulation time from days to minutes while maintaining accuracy, moving closer to real-time product design. Its applications include aerodynamic analysis for automobiles, thermal analysis of electronic components, and thermal fluid analysis of gasses.

RICOS aims to make scientific computation effectively usable in all manufacturing, envisioning a world where optimal performance can be designed instantly.
