Nvidia has taken the wraps off Omniverse Blueprint, a real-time physics engine designed to create digital twins. The software is optimized for computational fluid dynamics (CFD), allowing virtual exploration and refinement of objects that must function in the real world — things like automobiles, airplanes, ships — that are put to everyday use and tasked for production in the field and on set. One of the first use cases is a virtual wind tunnel that lets users simulate and visualize fluid dynamics at interactive speeds, even when changing the vehicle model as it navigates the tunnel.

Nvidia and Luminary Cloud, one of several partners, demonstrated the effect at the SC24 high-performance computing conference in Atlanta, where Nvidia founder and CEO Jensen Huang was a featured speaker along with the company’s VP of Accelerated Computing Ian Buck.

The blueprint is a reference workflow with standardized steps for setting up, running, and analyzing a simulation experiment using Nvidia’s library, including acceleration libraries, physics-AI frameworks and interactive render engines to achieve 1,200x faster simulations and real-time visualization.

“Traditional engineering workflows — from physics simulation to visualization and design optimization — can take weeks or even months to complete,” Nvidia explains in an announcement.

Luminary Cloud’s new simulation AI model was built on Nvidia Modulus, learning the relationships between airflow fields and car geometry using training data generated from its GPU-accelerated CFD solver. “The model runs simulations orders of magnitude faster than the solver itself, enabling real-time aerodynamic flow simulation that is visualized using Omniverse APIs,” according to Nvidia.

GamesBeat reports Ansys applied Omniverse Blueprint to its Ansys Fluent software to enable accelerated CFD simulation. “Ansys ran Fluent at the Texas Advanced Computing Center on 320 Nvidia GH200 Grace Hopper superchips,” completing “in just over six hours” a 2.5-billion-cell automotive simulation that “would have taken nearly a month running on 2,048 x86 CPU cores.”

Software developers including Altair, Cadence and Siemens are also experimenting with ways in which Omniverse Blueprint CFD digital twins can help customers reduce costs and energy usage while getting products to market faster, Nvidia says.

“Omniverse Blueprint is available on Nvidia DGX Cloud as well as leading alternatives like Amazon Web Services, Google Cloud, Microsoft Azure and Oracle Cloud Infrastructure,” explains TechRadar, noting “prospective customers can sign up for early access now.”
