Reynolds

Reynolds is Standard Physics’ agentic CFD: describe a flow in plain words; it writes and meshes an OpenFOAM case, solves on a hosted workspace, and returns figures, numbers, and a rerunnable case. MIT open source; pip install openreynolds.

Product: https://standardphysics.com/reynolds

Highlights:

• Flow: Describe → Build/mesh → Solve → Answer;
• Output is an ordinary OpenFOAM case experts can edit locally;
• Runs on vendor cloud, your infra, or a local CLI;
• Free for individual engineers with a verified work email (per site).

Why it matters

Wraps the OpenFOAM toolchain as “plain English → rerunnable case,” lowering CFD onboarding and providing a non-surrogate physics backend for products like Archimedes.

Caveats

• Complex industrial cases still need expert mesh/BC review;
• Disambiguate from the fluid-dynamics Reynolds number — use standardphysics.com/reynolds / OpenReynolds.

1. Try https://standardphysics.com/reynolds ;
2. pip install openreynolds and follow OpenReynolds docs/GitHub;
3. Describe a flow in plain English and inspect the returned case/figures;
4. For design search, see Archimedes.
