The landscape of scientific simulation and computational engineering is about to change dramatically. NVIDIA has unveiled Apollo, a groundbreaking family of open AI physics models designed to accelerate industrial and computational engineering across multiple industries. Introduced at the SC25 supercomputing conference in St. Louis on November 17, 2025, Apollo represents a quantum leap in how engineers and scientists approach simulation, design, and optimization.
The announcement has already attracted commitment from industry titans including Applied Materials, Cadence, LAM Research, Luminary Cloud, KLA, PhysicsX, Rescale, Siemens, and Synopsys, companies representing trillions of dollars in market value and touching virtually every aspect of modern manufacturing and design.
What Makes Apollo Revolutionary
Traditional physics simulation has been the backbone of engineering for decades. Whether designing aircraft, semiconductors, or predicting weather patterns, engineers rely on computational simulations to test concepts before building expensive physical prototypes. However, these simulations are computationally intensive, often requiring hours, days, or even weeks to produce results, severely limiting how many design iterations can be explored.
NVIDIA Apollo changes this equation fundamentally by using AI to accelerate physics simulations by orders of magnitude while maintaining accuracy. Rather than solving complex differential equations from first principles every time, Apollo's AI models learn the underlying physics and can predict outcomes in seconds rather than hours.
This isn't just incremental improvement, it's transformational. Engineers who previously could test dozens of designs can now explore thousands. Simulations that required overnight runs on supercomputers can now provide real-time feedback during the design process itself.
The Technology Behind Apollo
Apollo harnesses cutting-edge AI architectures specifically optimized for physics simulation:
Neural Operators: Advanced machine learning models that learn to map between function spaces rather than discrete points, enabling generalization to new scenarios not seen during training.
Transformers: The same attention-based architecture powering large language models, adapted for spatial and temporal patterns in physical systems.
Diffusion Methods: Probabilistic models that can generate realistic physics scenarios and handle uncertainty in predictions.
Domain-Specific Knowledge: Unlike generic AI models, Apollo incorporates fundamental physical principles, conservation laws, symmetries, and domain constraints, ensuring predictions remain physically plausible.
This combination allows Apollo models to achieve something remarkable: they're trained on data from conventional high-fidelity simulations, then can predict new cases with comparable accuracy but at speeds hundreds or thousands of times faster.
Six Critical Application Domains
Apollo addresses simulation needs across six fundamental areas of computational engineering:
1. Electronic Device Automation and Semiconductors
The semiconductor industry faces enormous computational challenges. Modern chip designs involve billions of transistors, and simulating their behavior, thermal characteristics, electromagnetic interference, lithography patterns, defect detection, requires massive computational resources.
Apollo's models enable near-real-time simulation of semiconductor manufacturing processes, allowing engineers to optimize designs and processes with unprecedented speed. Applied Materials has already achieved 35x acceleration in modules of its ACE+ multi-physics software using NVIDIA GPUs, and Apollo promises to accelerate this further.
2. Structural Mechanics
From automotive crash testing to aerospace structural analysis, understanding how materials and structures respond to forces is critical. Traditional finite element analysis (FEA) simulations can take hours or days for complex structures.
Apollo's structural mechanics models enable rapid exploration of design variations, material choices, and loading conditions, transforming structural optimization from a slow, sequential process to an interactive, real-time experience.
3. Weather and Climate
Climate modeling and weather forecasting require simulating the complex interactions of atmosphere, oceans, and land surfaces at multiple scales. Traditional climate models require supercomputers running for weeks to produce century-scale projections.
Apollo's weather and climate models can accelerate forecasting, enable higher-resolution regional predictions, and support data assimilation, incorporating real-world observations into models more effectively. This has implications not just for weather prediction but for climate change planning, agriculture, disaster preparedness, and renewable energy management.
4. Computational Fluid Dynamics (CFD)
Fluid flow simulation underpins design in aerospace (aircraft aerodynamics), automotive (vehicle aerodynamics and cooling), energy (turbine design, combustion), and manufacturing (chemical processing, cooling systems).
CFD simulations are notoriously computationally expensive, often requiring days on high-performance computing clusters. Apollo's CFD models enable real-time or near-real-time fluid simulation, dramatically accelerating design optimization.
Cadence demonstrated this capability by training an AI physics model on thousands of detailed aircraft simulations, enabling a real-time digital twin of a full aircraft, showcased at NVIDIA GTC Washington, D.C. last month.
5. Electromagnetics
Understanding electromagnetic behavior is crucial for wireless communication design, radar systems, antenna optimization, and high-speed optical data transmission. Electromagnetic simulations involve solving Maxwell's equations across complex geometries and frequency ranges, computationally intensive processes that limit design exploration.
Apollo's electromagnetics models accelerate these simulations, enabling rapid optimization of antenna designs, assessment of electromagnetic interference, and evaluation of wireless system performance.
6. Multiphysics
Many engineering challenges involve multiple interacting physical phenomena: nuclear fusion involves plasma physics, electromagnetic fields, and thermal dynamics; fluid-structure interaction combines fluid dynamics with structural mechanics. These multiphysics simulations are among the most computationally demanding in engineering.
Apollo's multiphysics capabilities enable simulation of these complex coupled systems at speeds that make design optimization practical rather than prohibitive.
Industry Adoption: Real-World Impact
The commitment from leading companies demonstrates Apollo's immediate practical value:
Applied Materials is using AI physics to develop new materials and manufacturing processes, achieving up to 35x acceleration and building AI models for material modification technologies. Their surrogate models enable near-real-time flow, plasma, and thermal modeling of advanced semiconductor process chambers, capabilities that were impossible with conventional simulation alone.
Cadence produced a high-quality dataset of thousands of time-dependent full aircraft simulations using its Fidelity CFD software on NVIDIA-powered supercomputers. The resulting AI physics model enables real-time digital twins of complete aircraft, transforming aerospace design workflows.
LAM Research is accelerating plasma reactor simulation, which is critical for semiconductor etching and deposition processes. Faster, more accurate plasma simulation accelerates development of next-generation semiconductor manufacturing equipment.
KLA will use Apollo models to accelerate simulations supporting development of semiconductor process control solutions, building on their existing capabilities in defect detection and metrology.
Northrop Grumman and Luminary Cloud are using NVIDIA AI physics for spacecraft thruster nozzle design. By generating large training datasets using CUDA-accelerated CFD solvers, they've built surrogate models that enable engineers to explore thousands of designs in record time, a capability that dramatically accelerates aerospace development.
PhysicsX's AI-native platform supports the complete AI lifecycle from simulation and data management to model training and deployment, seamlessly integrating with NVIDIA infrastructure and tools like Siemens Simcenter X. Their platform dramatically reduces product development cycles across automotive, aerospace, and energy industries.
Rescale is integrating Apollo models into its AI physics operating system, allowing engineers to seamlessly blend high-fidelity first-principles simulations with high-speed AI surrogates. This combination enables exploration of vast design spaces orders of magnitude faster while maintaining accuracy.
Siemens is integrating NVIDIA AI physics into Simcenter STAR-CCM+, its flagship fluid simulation tool. This allows designers to explore design options orders of magnitude faster than previously possible by blending traditional simulation with AI acceleration.
Synopsys is achieving up to 500x speedups in computational engineering by initializing GPU-accelerated simulations like Ansys Fluent with AI physics surrogates, dramatically reducing runtime compared to traditional initialization methods.
The Open Model Advantage
A critical aspect of Apollo is its open nature. NVIDIA is providing:
This openness accelerates adoption by eliminating the need for every company to independently develop AI physics capabilities from scratch. Companies can start with NVIDIA's pretrained models, fine-tune them on their specific data and applications, and integrate them into existing workflows.
Digital Twins and Real-Time Simulation
One of the most exciting applications of Apollo is enabling real-time digital twins, virtual replicas of physical systems that can predict behavior in real-time or faster. This capability transforms how engineers interact with simulations:
Instead of submitting a simulation job, waiting hours for results, analyzing them, modifying the design, and repeating, engineers can now adjust parameters and see results immediately. This interactive experience fundamentally changes the design process, enabling intuitive exploration of design spaces and rapid identification of optimal solutions.
For manufacturing, real-time digital twins enable predictive maintenance, process optimization, and quality control based on continuous simulation of actual operating conditions.
The Broader Impact
Apollo's impact extends beyond individual companies and industries:
Accelerated Innovation: Faster simulation means faster development cycles, accelerating the pace of innovation across all industries that rely on computational engineering.
Sustainability: More efficient design optimization reduces material waste, energy consumption, and environmental impact by enabling identification of optimal designs with fewer physical prototypes.
Democratization: By dramatically reducing computational requirements, Apollo makes sophisticated simulation accessible to smaller companies and developing nations that couldn't previously afford supercomputer time.
Scientific Discovery: Researchers can explore more hypotheses, test more theories, and analyze more data, accelerating scientific discovery in fields from climate science to fusion energy.
Economic Competitiveness: Nations and companies that adopt AI-accelerated simulation will gain significant competitive advantages in time-to-market and design quality.
