Editor’s note: This post is part of Into the Omniverse, a series focused on how developers, 3D practitioners and enterprises can transform their workflows using the latest advances in OpenUSD and NVIDIA Omniverse.
Computer-aided engineering (CAE) is at the forefront of modern product development, enabling engineers to virtually test and refine designs before building physical prototypes. Among the powerful CAE methods, computational fluid dynamics (CFD) simulation plays a critical role in understanding and optimizing fluid flow for use cases, such as aerodynamic testing in aerospace and automotive engineering or thermal management for electronics.
The NVIDIA Omniverse Blueprint for real-time digital twins provides a powerful framework for developers to build complex CFD simulation solutions with the combined power of NVIDIA CUDA-X acceleration libraries, NVIDIA PhysicsNeMo AI framework and NVIDIA Omniverse, and Universal Scene Description (OpenUSD).
Multiphysics simulation generates a high diversity of data with optical, thermal, electromagnetic and mechanical applications, all requiring different inputs and outputs.
OpenUSD provides a unified data model that connects the CAE ecosystem so digital twins can operate in real time with diverse data inputs. This seamless interoperability between tools is crucial for engineering efforts that rely on accurate, consistent CFD simulations.
Industry Leaders Deliver 50x Faster Simulation
At NVIDIA GTC in March, NVIDIA announced that leading CAE software providers, including Ansys, Altair, Cadence, Siemens and Synopsys, are accelerating their simulation tools, including for CFD, by up to 50x with the NVIDIA Blackwell platform.
Thanks to accelerated software, NVIDIA CUDA-X libraries and performance-optimization blueprints, industries like automotive, aerospace, energy, manufacturing and life sciences can greatly reduce product development time and costs while increasing design accuracy and remaining energy efficient.
Ansys, a leader in simulation software, is harnessing the power of NVIDIA technologies for real-time physics and accelerated simulation with AI-driven digital twins. By integrating NVIDIA GPUs and tapping into Blackwell’s advanced accelerated computing capabilities, Ansys software enables engineers to run complex CFD simulations at unprecedented speed and scale.
Real-Time Digital Twins for CFD
Ansys is also adopting Omniverse and OpenUSD to create more connected, collaborative simulation environments for CFD. Ansys users can build real-time digital twins that integrate data from multiple sources, and now those multidisciplinary CFD simulations can be integrated into the visually rich Omniverse environment.
