Insights
Ansys's partnership with Volvo Cars and NVIDIA represents a significant technological advancement with positive business implications. The 2.5X acceleration in computational fluid dynamics (CFD) simulation times for the Volvo EX90 electric vehicle - reducing processing from 24 hours to 6.5 hours - addresses a critical bottleneck in automotive design.
The breakthrough enables multiple design iterations daily rather than just one, potentially accelerating product development cycles significantly. For Ansys, this showcases their software's technical capabilities when paired with advanced hardware, creating a compelling value proposition: Volvo achieved these results using just 8 NVIDIA Blackwell GPUs versus 2,016 CPU cores in the comparison case.
This development is particularly relevant in the EV market where aerodynamic efficiency directly impacts vehicle range - a key competitive differentiator. The explicit mention of helping meet critical standards like the Worldwide Harmonized Light Vehicles Test Procedure (WLTP) requirements positions Ansys's solution as addressing regulatory compliance challenges.
The timing alongside NVIDIA's GTC conference maximizes industry visibility, potentially attracting customers from aerospace, motorsports, and consumer electronics who face similar computational challenges. While no financial terms were disclosed, this collaboration demonstrates Ansys's ability to deliver performance improvements that directly address time-to-market pressures across multiple industries.

/ Key Highlights
- Ansys Fluent® fluid simulation software delivers high-fidelity computational fluid dynamics (CFD) models that are critical for designing next-generation, energy-efficient vehicles
- Leveraging just eight NVIDIA Blackwell GPUs, Ansys accelerated solver speed by 2.5X when compared to the same simulation run on 2,016 CPU cores and cost-equivalent hardware
- Using Ansys simulation to reduce aerodynamic drag, customers can design battery electric vehicles (BEVs) that are more performant and travel farther on a single charge
Volvo Cars relies on advanced computing and CFD to drive innovation and improve electric battery performance. Robust simulations are critical for reducing aerodynamic drag — a significant factor on EV range. However, high-fidelity CFD simulations can be time consuming, compute-intensive, costly, and allow little opportunity for optimization.
To improve the energy efficiency and drive range of the fully electric EX90, Volvo Cars and Ansys scaled Fluent to eight NVIDIA Blackwell GPUs, enabling an optimized end-to-end workflow wherein meshing only took one hour and the solver took 5.5 hours. Compared to solving the same simulation on cost-equivalent hardware using 2,016 CPU cores, this equates to a 2.5X speed increase in solve time. The technology combination can allow Volvo Cars to run multiple CFD simulations per day, evaluating a range of design variants to quickly enable a step change in design optimization.
"Using Ansys simulation has the potential to help our teams obtain favorable designs and carry out virtual testing in much less time than traditional approaches allow," said Torbjörn Virdung, technical leader CFD, at Volvo Cars. "To make our products more efficient, we must first take stock of the tools and solutions we're using to get there. In this case, the capability of Ansys Fluent can allow us not only to perform extremely high-fidelity analyses, but the added NVIDIA infrastructure supercharges the computation, so we can consider a greater number of design possibilities and reach an optimal car design faster."
This accelerated process has the potential to further help Volvo Cars meet critical emissions, range, and efficiency standards, such as Worldwide Harmonized Light Vehicles Test Procedure (WLTP) requirements.
"This breakthrough underscores how GPU-accelerated simulation can drive innovation and get products to market faster," said Shane Emswiler, senior vice president of products at Ansys. "The combination of high-fidelity modeling and extreme solver speed empowers customers to run more simulations and maximize the results to develop more performant products."
"The efforts of Ansys and Volvo Cars showcase the exceptional performance and scalability of our latest
