Physics-first · GPU-native

High-fidelity CFD, rebuilt for the GPU era.

Nabla AI is building a physics-first, GPU-native simulation engine that dynamically concentrates compute where it matters most.

The problem

High-fidelity simulation remains too slow and too manual.

A single trustworthy result can take days or weeks — most of it spent preparing the simulation rather than learning from it. Today's high-fidelity CFD workflows still depend on:

  • Manual meshing and geometry clean-up
  • Hand-tuned models, solvers and parameters
  • Uniform or poorly allocated resolution
  • Long iteration cycles
  • Expensive compute infrastructure
  • Highly specialised engineering teams

Technology

A simulation engine that understands where compute matters.

Resolution is treated as a dynamic resource — allocated in space and time by the physics of the flow, not fixed upfront by a mesh.

01

Dynamic resolution allocation

The engine continuously reallocates computational resolution toward shocks, vortices, boundary layers and other physically relevant structures — instead of spending compute uniformly across the domain.

02

Automated solver orchestration

Nabla AI selects and coordinates numerical methods, fidelity levels and solver configurations based on the evolving flow — no manual tuning loop.

03

GPU-native architecture

The complete simulation pipeline is designed around modern GPU hardware, rather than adapted from legacy CPU-based architectures.

04

Configurable fidelity

Users can balance speed and accuracy across a spectrum ranging from engineering-grade LES to near-DNS fidelity, per case and per question.

Approach

Not another CFD surrogate model.

Neural surrogates trained on libraries of precomputed simulations can be extremely fast — but they inherit the limits of their training data and offer no physical guarantees on genuinely new designs. Nabla AI is a numerical simulation engine first; machine learning enters only where it accelerates the physics without compromising it.

  • Physics-first numerical simulation
  • Adaptive computation
  • GPU-native execution
  • Machine learning where it creates measurable value
  • Physically consistent outputs
  • Generalisation beyond narrow training distributions

Traditional CFD

  • Physically rigorous
  • Slow and manual
  • Expensive
  • Complex workflows

Pure AI surrogate

  • Extremely fast
  • Limited generalisation
  • Training-data dependent
  • Hard to trust

Applications

One engine, multiple engineering domains.

The same adaptive core applies wherever turbulence, heat and high-speed flow decide how a product performs.

01

Aerospace

Aerodynamics, propulsion, hypersonics and complex turbulent flows.

02

Automotive

External aerodynamics, thermal management and design optimisation.

03

Energy

Wind, combustion, heat transfer and next-generation energy systems.

04

Turbomachinery

Compressors, turbines and rotating flows requiring high-resolution simulation.

05

Defence

High-speed flows, propulsion, autonomous systems and complex mission environments.

06

Industrial flows

Multiphysics and turbulent flows across advanced manufacturing and infrastructure.

Vision

Simulation should become an interactive engineering tool.

Instead of waiting days for a simulation result, engineers should be able to explore designs, test hypotheses and iterate at the speed of thought.

Nabla AI is building the computational layer that makes this possible.
