GPU Acceleration

GPU acceleration is transforming high-fidelity CFD, massively impacting aerospace, automotive, turbomachinery, and many other industries. Leveraging GPU computing for CFD unlocks engineering efficiency. For a given investment in computing, the Fidelity LES solver provides an up to 10X increase in throughput relative to CPU. For a fixed simulation throughput, the reduction in energy requirement of GPU computing versus CPU computing is about 17X.

Scalability

Millennium M1 provides near-linear scaling across applications, from external aerodynamics and aero-acoustics to combustion and multiphysics. It enables massive LES simulations with the fastest time to results—such as the accurate simulation of a realistic aircraft in landing configuration, in under 14 hours on just two GPU nodes.

High-Fidelity LES

The Fidelity LES solver within Millennium M1 combines advanced numerical methods and models, providing cost-effective, high-throughput simulation via GPU acceleration. Unique solver discretization combines with the latest sub-grid scale and wall modeling to offer an LES capability that delivers remarkable robustness to grid resolution.

Automotive LES

The aerodynamics of a car play a significant role in determining the driving range of battery electric vehicles and the fuel economy/greenhouse gas (GHG) footprint of internal combustion engine (ICE) vehicles. As designers develop automobile aerodynamics, they need to evaluate several design considerations. Lack of accuracy in the simulation tool can result in small improvement opportunities going unnoticed or, worse, driving the design in the wrong direction.

The Fidelity LES solver in Millennium M1 provides the accuracy and precision needed for predicting aerodynamic forces with wind-tunnel accuracy in turnaround times previously achieved only with lower-fidelity methods.

Aerospace

Millennium M1 enables designers to predict aerodynamic forces for complex geometries over a range of flow regimes from low-Mach to transonic and supersonic. Changes in vehicle drag due to subtle geometric design modifications can be captured and the onset of stall over high angle of attack airfoils on a commercial aircraft can be captured.

Turbomachinery

Millennium M1 is transforming high-fidelity CFD, reducing the turnaround time for LES simulations from days to hours. Multiple high-fidelity simulations can be performed in a single day, allowing exploration of complex design spaces with unprecedented speed and accuracy and enabling large digital twin simulation and analysis.

“ASUS is excited to work with Cadence on their new Millennium platform, which delivers exceptional performance and energy efficiency through Cadence’s revolutionary combination of hardware and software. We look forward to our continued partnership to address AI-enabled digital twin designs…”

“The combination of Cadence Fidelity CFD software and GPU computing has increased our high-fidelity simulation throughput by up to 8X for our subsonic applications. Given the large volume of simulations we run, we expect the Millennium M1 to have a positive impact on our workflow in terms of speedup and accuracy.”
