Agentic physics simulation for

Simulation that sets itself up, runs, and answers questions. 1000× faster than traditional CFD.

The Problem

You simulate once a quarter.
Physics changes every second.

Physics simulation is slow, expensive, and needs a specialist to set up every case. So engineering teams run it rarely, and act on answers that went stale months ago.

Products

One engine. Two ways to run it.

Agentic simulationProduction

Reynolds

Sets up the case, runs the solver, checks convergence, and answers questions in natural language. Solver-agnostic by design.

Continuous operationLive

Control

The same engine pointed at live telemetry. Buildings, data centers, HVAC.

Explore Control

Same engine. Run it once and it is analysis. Run it every fifteen minutes against live data and it is control.

Data center thermal twin. Drag to rotate, scroll to zoom.

Digital Twin

Physics-informed AI, built for the real world.

One example of what the engine produces: a thermal twin you can rotate, query, and interrogate. Every field you see is a real numerical solution from an open source solver, not an approximation, so every answer can be inspected down to the case setup.
