Computer-aided engineering (CAE) has become indispensable in modern product development, with computational fluid dynamics (CFD) simulation playing a vital part in optimizing designs for fields such as aerospace, automotive, and electronics. NVIDIA is advancing this domain by integrating its Omniverse platform, Universal Scene Description (OpenUSD), CUDA-X acceleration, and Artificial Intelligence frameworks like PhysicsNeMo. This ecosystem allows developers to build and run high-fidelity, real-time digital twins, enabling designers and engineers to virtually test and refine products before physical prototyping.
NVIDIA´s Omniverse Blueprint for digital twins streamlines the construction of complex CFD simulation solutions. Multiphysics simulation, which covers a range of data from optical and thermal analysis to electromagnetic and mechanical properties, is unified through OpenUSD, fostering open interoperability between previously siloed CAE tools. This ensures accurate and consistent simulations, underpinned by seamless real-time data exchange, facilitating collaboration and iterative product development across multiple organizations and teams.
The industry has taken a significant leap forward with NVIDIA´s Blackwell platform. During NVIDIA GTC, top CAE software providers like Ansys, Altair, Cadence, Siemens, and Synopsys announced up to 50x speed improvements in their simulation engines, including for CFD tasks, thanks to this platform´s accelerated computing. These advancements drastically reduce turnaround time and operational costs while enhancing design accuracy and sustainability. Ansys, in particular, has embraced the latest NVIDIA technologies to integrate Artificial Intelligence-driven workflows and real-time physics in simulation, offering engineers the capability to construct multidisciplinary digital twins that plug into Omniverse´s collaborative, visually immersive environment.
As NVIDIA continues to promote the adoption of accelerated computing and 3D workflow interoperability, engineers and 3D practitioners can leverage a host of free learning resources, industry events, and user communities to further their expertise. Events such as NVIDIA GTC Taipei at COMPUTEX and the global Ansys Simulation World spotlight the future of digital twins and computational simulation powered by Artificial Intelligence, OpenUSD, and Omniverse. Ongoing educational programs, like the ´Learn OpenUSD´ curriculum, support developers aiming to unlock new potential in real-time simulation and next-generation engineering design workflows.
