Ansys is a leading engineering simulation company, and its software is a primary workload on many OCF-built HPC systems. With Ansys 2025 R1 and subsequent releases, engineering simulation is becoming faster, smarter, and more efficient through AI-driven simulation, GPU acceleration, system-level modelling, and cloud computing.

• Ansys solvers, Fluent (CFD), Mechanical (FEA), HFSS (electromagnetics), LS-DYNA (explicit dynamics) are engineered for massive parallel scalability, routinely scaling to thousands of cores. Ansys' HPC licensing models (HPC Packs) and close collaboration with hardware vendors mean OCF can size and tune clusters specifically for simulation throughput, directly translating hardware investment into faster design cycles for engineering and manufacturing customers.
• Ansys workloads drive requirements for high-bandwidth scratch storage, which OCF addresses through its parallel file system partners such as IBM.
• GPU-native solvers (notably Fluent's multi-GPU capability) can replace dozens of CPU nodes with a handful of GPUs, reshaping cluster design.

Ansys is well trusted with validated solvers that organisations bet their products on and which are increasingly accelerated by GPUs and AI.
