Overview
Millennium M1 Accelerates CFD System Design and Analysis
Computational fluid dynamics (CFD) simulations have been widely used to shorten lengthy design cycles and reduce the number of costly experiments. However, the accuracy and speed limitations of traditional CFD solver technology and computing resources have limited the potential for CFD analysis. These challenges have typically prevented CFD users from efficient virtual engineering.
The Cadence Millennium M1 CFD Supercomputer, the industry’s first turnkey CFD solution, overcomes these obstacles with a combination of best-in-class graphic processing unit (GPU) resident CFD solvers such as the Cadence Fidelity LES Solver for large eddy simulations (LES) and scalable high-performance computing (HPC) hardware to unleash unprecedented performance. Rapid generation of high-quality synthetic data enables generative AI to quickly identify optimal system design solutions without compromising accuracy.
Millennium M1 extends the practical application of LES in aerospace, automotive, power generation, and turbomachinery applications by reducing turnaround time from days to hours.

Applications
Expanding Practical Application of High-Fidelity LES
Millennium M1 enables designers to improve engineering efficiency for a broad range of applications. It provides a modern modular and scalable HPC architecture preloaded with Cadence’s Fidelity CFD software—unlocking performance like never before.
Automotive
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.
