Open-source CFD · MCP-native

AI engineering simulation that shows its work.

Describe a CFD problem in plain English. SimPrompt generates an editable OpenFOAM setup, runs the real solver, and returns a validated report. The engineer approves the schema before anything runs — and walks away with the case files.

Three panels: a plain-English CFD prompt, an editable case.yaml schema, and the resulting OpenFOAM run with pressure field and residuals plot.

What we simulate

External aerodynamics across four wedge sub-niches today. Each tile is a schematic of the kind of result you get back — same OpenFOAM underneath, same case files in your hands at the end.

How it works

Three steps. The AI is on either side of the solver — never inside it.

01

Describe in plain English

"Simulate flow over an Ahmed body at 25 m/s." The Intent Agent generates an editable SIS-CFD schema — your controlDict, fvSchemes, and boundary conditions as YAML.

02

Approve the schema

Review the YAML in the Schema Viewer. Edit any field. Nothing runs until you click approve. This is the trust gate — no surprises.

03

Real solver, real logs

OpenFOAM runs on AWS Batch. You see the actual solver output. The Evaluator Agent summarises results and flags convergence issues. Case files exportable, always.

Why SimPrompt and not the alternatives

Other AI-CFD tools exist. SimPrompt's three durable differences:

Open OpenFOAM

Real OpenFOAM. Not a proprietary fork. Not a black-box surrogate. You can take the case files and run them anywhere — on-prem, on your AWS account, on a dusty workstation under the desk.

Schema visibility

The SIS-CFD YAML is editable before every run. You see what physics you're about to solve. No hidden defaults. No “trust the model.”

Project-export rights

Your case files. Your schema. Your validation report. Take them with you. We don't lock your work behind a per-seat licence.

Benchmarks

We will not publish a number we cannot reproduce. Currently building.

NACA0012 — lift & drag at αNASA TMR— pending —Targeting Week 4

When we publish, we publish the case files, the schema YAML, and the reproducibility recipe. If you can't re-run our number, we don't ship the number.

Join the waitlist

We are looking for senior CFD practitioners as design partners. If you run OpenFOAM commercially, you're exactly who we want to talk to.

No tracking pixels. No spam. We email when there's something worth showing — typically once every benchmark cycle.
