Ansys announced a significant milestone, achieving a 110x acceleration in computational fluid dynamics (CFD) simulation using Ansys Fluent on NVIDIA GH200 Grace Hopper Superchips. This breakthrough reduced the overall run time for a large-scale CFD simulation from four weeks to just six hours. The accomplishment demonstrates Ansys' commitment to pushing innovation boundaries and amplifying complex simulation across various industries.
The record-breaking simulation involved a 2.4-billion-cell automotive external aerodynamics model, run in collaboration with NVIDIA using advanced computing capabilities at TACC. This acceleration was achieved with 320 GH200 Grace Hopper Superchips, providing performance equivalent to approximately 225,390 CPU cores. This allows for significantly faster design cycles and the ability to add more parameters for refined accuracy without compromising simulation speed.
Large-scale CFD simulations are typically complex and time-consuming, often taking days or weeks on CPU cores. By harnessing the power of GPUs, Ansys solutions deliver pervasive insights in a fraction of the time while maintaining high predictive accuracy. Ansys is also the first to adopt an Omniverse Blueprint, a reference workflow of NVIDIA acceleration libraries, for real-time, interactive physics visualization in its applications.
