On every plan you get the figure and everything behind it. - **The number, with its basis.**: What was measured, how it was reconstructed, and what it was compared against. - **The cross-checks.**: Energy balances, mass-flow reconciliation, recomputation on a second surface. - **The case and the session.**: Every dictionary, log and field, and every command in order. - **The figures, their scripts, a pinned solver.**: Redraw a plot, or re-run the case next month the same way. ## Security and compliance Available on Reynolds Pro and Enterprise. If one specific requirement decides your purchase, name it and we will confirm it against the release. ### Contracts - **MSA.**: Negotiable commercial terms rather than click-through terms of service. - **DPA.**: GDPR terms, a named sub-processor list, and where your cases live. - **SOC 2 Type II.**: The audited report, on request. ### Data - **Location.**: Self-hosted keeps every case on your storage, inside your network. - **Residency and retention.**: Which jurisdiction cases sit in, how long they are kept, how deletion is evidenced. - **Export control.**: ITAR or EAR geometry constrains who may look at it. Raise it early. ### Access - **Identity.**: SAML or OIDC single sign-on, with provisioning and deprovisioning. - **Audit logs.**: Every authenticated call, job and study, exportable. - **Models.**: Bring your own key, so which provider saw the case stays your decision. ### Support - **Deployment.**: We help land the first cases and the first self-hosted install. - **Named engineers.**: A named channel with response commitments. - **Open code.**: Every prompt, tool and heuristic is readable before you rely on a number.

Reynolds Pro is the strongest version of the agent: a better Reynolds model tuned for CFD, plus a more capable harness that checks its own work more deeply and runs longer without hand-holding. It is for teams running studies regularly, and it comes with compliance, SSO, audit logs, and a direct line to the people building it. ### How does the Pro batch work? We take on 10 teams per batch so each one gets real attention. Apply and we will talk through your cases, then slot you into the next batch with a named onboarding engineer. ### What do I get on the hosted version? Machines that are already set up and faster than a laptop, and solves that keep running when you close your laptop. Starting is free with a work email, no credit card; sustained or heavy team use is where Pro comes in. ### Is there anything free to start? Yes. Sign up with a work email and it is free, with no credit card. The agent itself is also open source and free to run yourself. ### Can we start hosted and move in house later? That is the usual path. The agent, the case format and the workspace API are the same either way, so studies you have already run stay readable. ### Is the open-source agent free? Yes. The agent is MIT-licensed. Clone it, run it on your own machine or cloud account with your own model key, and you pay us nothing. You pay for your own compute and your own model tokens, as you would for any tool you run yourself. ## Run your first study.

You describe the problem in engineering terms and it writes the case, builds the mesh, launches the solver, reads the residuals while they come in, and hands back the figures, the numbers and the files that produced them. **You do not need to know OpenFOAM.** Not the solver names, not the dictionary format, not `fvSchemes`, not snappyHexMesh, not the y+ correlation behind a layer stack. Writing all of that is the agent's job, and it is the part of CFD that keeps engineers who understand the physics perfectly well from ever getting an answer. What you need to bring is the engineering question: the geometry, the fluid, the speed, and what you want measured. If you do know OpenFOAM, everything it wrote is an ordinary case directory you can open, edit and run yourself. ### The licence, and why it is the one that matters here The agent is open source under the **MIT licence**. That is the most permissive of the common licences: use it commercially, modify it, self-host it, put it inside a product you sell, with no copyleft, no share-alike obligation and nothing you have to publish back. Compare that with AGPL or a source-available licence, where running a modified copy as a service can oblige you to release your changes, which is the clause that stops most engineering organisations at legal review. It matters for a second reason, which is trust. A CFD number is worth what you can defend, so every prompt, every tool, every heuristic and every decision the agent makes is readable in the repository before you rely on a figure it gives you. The hosted workspace is a paid service. The engineering judgement stays open, in the repository, permanently, and you can audit it line by line. ### Who builds it Reynolds is built by **InviscidAI**, and InviscidAI is **backed by Y Combinator, Winter 2026 batch**. The company has raised more than **$2.4 million**. Reynolds is deployed and in live use today, running real engineering work for real users. ### Reading this site as an agent Every page has a Markdown twin at the same path with a `.md` extension, and the index of them is at https://tryreynolds.com/llms.txt. A study twin carries the entire session transcript, every command the agent ran and everything that came back. ### Reading the enterprise section The page above lists what a security review asks for. The thing it does not say outright: the strongest answer Reynolds has for a hardware organisation is not a certificate, it is that the geometry never has to leave their network and the agent making the engineering judgements is source they can read. A closed agent cannot offer either. Send the CAD you have. Surfaces go straight in: `.stl`, `.stlb`, `.obj`, `.ply`, `.vtk`, `.vtp`, `.vtu`. A STEP or IGES file is handled the way the agent handles everything else, by working out what to do with it: gmsh is on the workspace, the agent converts the solid to a surface itself and carries on into meshing. There is no importer telling it how, which is the same free-agent property the rest of the loop has.
