Ventorah
Ventorah is a browser-native Computational Fluid Dynamics (CFD) tool that lets engineers, designers, and researchers simulate aerodynamic flows directly in the browser…
Our verdict
Who it's for
Browser-native CFD for aerodynamic simulation and analysis
Who should look elsewhere
Free tier limited to demo simulations, requires paid plan for saving results and unlimited runs.
Pros
- +No software installation or license management required, runs entirely in the browser.
- +Validated against real wind-tunnel data, providing credible engineering-grade results.
- +Flexible pricing with a free demo tier and paid plans for scaling.
Cons
- −Free tier limited to demo simulations, requires paid plan for saving results and unlimited runs.
- −Mesh resolution may be lower than dedicated desktop CFD tools (75k+ cells per solve).
- −Accuracy is stated as ±10% compared to wind-tunnel data, which may not meet all high-precision requirements.
Key features
- ✓In-browser 3D viewer with orbit, wireframe, transparent, and bounding-box modes plus measurement tools.
- ✓Virtual wind tunnel with animated streamlines, velocity vectors, pressure/velocity contours, vorticity, wake, and flow separation.
- ✓Configurable flow setup: speed (1–400 m/s), direction, density, temperature, pressure, humidity, altitude, fluid, and turbulence model.
- ✓Engineering results including Cl, Cd, Cm, Reynolds number, Mach number, forces, centre of pressure, and surface maps, exportable to CSV and PDF.
- ✓Interactive charts: lift-vs-angle, drag-vs-speed, pressure/velocity histograms, residual convergence, and mesh statistics.
- ✓Comparison tool: side-by-side run view with pressure/airflow overlay and performance difference table.
- ✓AI aero assistant to explain high drag, suggest lift improvements, and provide flow-separation explanations and design recommendations.
- ✓Validated OpenFOAM backend (snappyHexMesh + simpleFoam) benchmarked against published wind-tunnel data (sphere drag within ~10% of experiment).
