PITTSBURGH, April 1, 2025 /PRNewswire/ --  Ansys (NASDAQ: ANSS) today announced groundbreaking results from the largest commercial Fluent CFD simulation ever run on AMD Instinct™ MI250X GPUs. Leveraging the power of the Frontier exascale supercomputer, powered by AMD EPYC™ CPUs and Instinct GPUs, Ansys and energy company Baker Hughes scaled Fluent to 1,024 GPUs, offering unparalleled insight into aerothermal physics at large operating pressures. By pairing physical tests with virtual ones, Ansys simulation helps customers achieve faster design cycles and optimizes development costs.

Traditional CFD methods involve lengthy development cycles and high costs for validating designs under extreme conditions. Exascale supercomputing systems supercharge computation, allowing for rapid iterations that shorten design-to-market timelines across applications. The combination of advanced hardware and leading multiphysics simulation software is pivotal for optimizing the development of turbine engines, power generation, mechanical drives, and more.

Baker Hughes uses Ansys Fluent to support the design of its next-generation gas turbines and other turbomachinery equipment to improve energy conversion efficiency and ultimately, reduce carbon footprints. Using the Frontier exascale supercomputer maintained by the Department of Energy's Oak Ridge National Laboratory, Baker Hughes and Ansys ran a 2.2-billion-cell axial turbine stator simulation to identify critical flow and turbulence structures during the development phase.

When comparing this to methods that utilize over 3,700 CPU cores, Baker Hughes and Ansys reduced the overall simulation run time from 38.5 hours to just 1.5 hours using 1,024 AMD Instinct MI250X GPUs. This record-breaking scaling allows for faster design iterations and more accurate predictions, capable of unlocking more sustainable technologies and products.

The advancements in the Fluent GPU solver also offer significant benefits to small and medium-sized businesses (SMB) operating on smaller GPU systems. With the solver's improved computational efficiency and scalability, SMBs can achieve high-fidelity simulations without needing access to exascale resources.

"By scaling high-fidelity CFD simulation software to unprecedented levels with the power of AMD Instinct GPUs, this collaboration demonstrates how cutting-edge supercomputing can solve some of the toughest engineering challenges, enabling breakthroughs in efficiency, sustainability, and innovation," said Brad McCredie, senior vice president, Data Center Engineering, AMD.

"Ansys works with top-tier hardware partners like AMD to deliver robust infrastructure, empowering our customers to run complex simulations with minimal constraints," said Shane Emswiler, senior vice president of products at Ansys. "Our advanced GPU-enabled solvers can boost simulation speeds, allow for very high-fidelity simulation, and enhance scalability — helping our customers develop superior products in much shorter timelines."
