Multiple GPU architecture provides the performance necessary for complex Multiphysics and CFD analysis applications

The Millennium Platform accelerated digital twin provides CFD multiphysics analysis capabilities in the cloud

The Cadence Millennium Enterprise Multiphysics Platform from Cadence Design Systems is a combination of hardware and software that has been developed to provide an accelerated digital twin approach to multiphysics system design and analysis.

An example of its application is for use with high-fidelity computational fluid dynamics (CFD) simulations. Available as a server-based Software as a Service (SaaS) model in the cloud or as a full on premises installation, it includes graphics processing units (GPUs), extremely fast interconnections and an enhanced Cadence high-fidelity CFD software stack optimised for GPU acceleration and generative AI.

Designing mechanical systems for current high levels of performance and efficiency on a background of fundamental industry changes has become a key priority in the automotive, aerospace and defence (A&D), energy and turbomachinery industries.

As an example, within the automotive industry, in order to optimise performance and reduce greenhouse gases, car manufacturers are demanding that their designers become more focused on improvements in fuel efficiency, a reduction in drag, noise, vibration and harshness as well as extensions to the range of electric vehicle.

In aerospace and defence, design engineers are also engaged in projects aimed at Increasing efficiency, reducing carbon emissions and reducing maintenance frequency.

In both of these industries, advances in multiphysics simulation technology are providing technological assistance in achieving these goals and CFD is a crucial aspect of this. Performance, accuracy, capacity and accelerated computing are all essential to enabling digital twin simulations that explore more design innovations and providing confidence that they will function as intended before undertaking prototype development and testing.

Multiphysics Simulation Platform

Running CFD simulation alongside other physics based solving challenges requires high performance computation combined with the necessary software for performing the task. By combining GPU-resident CFD solvers with dedicated hardware, the Millennium Enterprise platform has the capacity to handle the computational challenges and is able to provide significantly reduced turnaround times for solving complex CFD models with high levels of accuracy.

AI Digital Twin

Described by cadence as being an AI Digital Twin, the system enables the rapid generation of high-quality multiphysics data with generative AI to create fast and reliable digital twin visualisations of optimal system designs.

The system is scalable due to its architecture, which couples GPU computing with accelerated CFD solvers. Multiple configurations are available with at least 8 GPU configurations for cloud based computing and 32 configurations if the system is installed on the user’s premises.

According to Ben Gu, corporate vice president of R&D for multiphysics systems analysis at Cadence, the company has been focused on increasing performance with no loss of accuracy for the most challenging computational applications. Algorithmic throughput remains a key priority, with generative AI now being used in order to make the most of the knowledge that has been gained from the massive quantities of design and simulation data that has long been available but which is now more accessible through the use of artificial intelligence.

“CFD is poised to benefit greatly from these performance and efficiency gains, and the tremendous power of the Millennium M1 platform is providing another means for industries to explore more design innovations and bring them to market,” he says.
