OpenFOAM external aerodynamics · 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.
You approve the setup schema before any solver run.
What we simulate
External aerodynamics on OpenFOAM, across four sub-niches. Same SIS-CFD schema underneath, same case files in your hands at the end.
Vehicle aerodynamics
Ahmed-body and production-vehicle external aero. Drag, lift, and surface-pressure fields, exported as OpenFOAM case files.
Steady · incompressible · k-ωSST · single-phase
Pedestrian wind comfort
Urban-canyon wind at pedestrian height. Velocity contours and comfort criteria, ready for planning-permit reports.
Steady · incompressible · k-ωSST · single-phase
Wind-turbine blades
Blade-section external aero with boundary-layer resolution. Pressure-coefficient distributions for design iteration.
Steady · incompressible · k-ωSST · single-phase
Drone & UAV propellers
MRF rotating-frame boundary conditions are first-class. eVTOL, FPV, and small-UAV teams iterate on rotor geometry in days.
Steady · incompressible · k-ωSST · single-phase
How it works
Three steps. The AI is on either side of the solver — never inside it.
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.
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.
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.
| Benchmark | Reference | SimPrompt result | Status |
|---|---|---|---|
| Ahmed body — drag coefficient | Ahmed (1984) | — pending — | Targeting Week 4 |
| NACA0012 — lift & drag at α | NASA TMR | — pending — | Targeting Week 4 |
| NASA TMR turbulence cases | turbmodels.larc.nasa.gov | — pending — | Targeting Week 6 |
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.
