In-browser 3D model viewer
Upload STL, OBJ, STEP, IGES, GLB, or FBX files and inspect them immediately in a WebGL viewer with orbit, wireframe, transparent, and bounding-box modes.
Ventorah
RivendicaVentorah is a browser-based CFD tool for virtual wind tunnel analysis on uploaded 3D models, with run, review, and export workflows.
Browser CFD for virtual wind tunnel analysis
Ventorah is a browser-based CFD product for running virtual wind tunnel studies on uploaded 3D geometry. The site describes it as “Browser CFD” and supports common model formats including STL, OBJ, STEP, IGES, GLB, and FBX.
The workflow covers geometry upload, flow-condition setup, meshing and solving, and review of flow fields and engineering outputs in the browser. Results include streamlines, pressure fields, lift and drag, coefficients, charts, and exportable reports, which makes the product useful for aerospace, automotive, and drone aerodynamics work.
Core features
Configurable flow setup
Set wind speed, direction, density, temperature, pressure, humidity, altitude, fluid, turbulence model, and mesh resolution before starting a solve.
Virtual wind tunnel visualization
Run simulations that produce streamlines, velocity vectors, pressure and velocity contours, vorticity, wake, and flow separation as the solve progresses.
Engineering outputs and export
Read lift, drag, and moment coefficients, Reynolds and Mach numbers, forces, centre of pressure, and surface maps, with CSV and PDF export options.
Run comparison workflow
Compare two runs side by side, overlay pressure and airflow, and inspect a difference table for performance changes.
AI-assisted analysis
Use the built-in AI aero assistant to ask about drag, lift, flow separation, and design recommendations, with AI features running on the user’s Anthropic API key.
Where Ventorah fits
Aerospace concept studies
Evaluate lift, drag, and flow separation on airfoils, bodies, and other geometry without setting up a local CFD environment.
Automotive aerodynamics
Review exterior airflow and pressure distribution on car-shaped models or components during early design iterations.
Drone and UAV design
Assess drag and wake behavior on drone frames or other small aircraft parts before moving to physical testing.
Design iteration and comparison
Run multiple simulations with different flow conditions, then compare the resulting coefficients and pressure overlays side by side.
Reporting and review
Generate CSV or PDF outputs that can be shared with teammates or used in engineering documentation.
Pros and Cons
Pros
- Runs CFD in the browser, so there is no install or license server in the documented flow.
- Supports a full pre/solve/post workflow from geometry upload through results review.
- Accepts multiple common CAD and mesh file formats.
- Provides concrete engineering outputs such as coefficients, forces, charts, and surface maps.
- Includes a side-by-side comparison tool for reviewing two runs.
Cons
- The public pricing page returned 404 in the collected sources, so plan details are not fully published there.
- The AI assistant depends on the user’s own Anthropic API key, which adds a setup step for those features.
- The source does not show integration details beyond export to CSV/PDF and connecting an OpenFOAM worker or Claude key.
FAQ
What does Ventorah do?
Ventorah is a browser-based CFD tool. You upload a 3D model, set flow conditions, run a simulation, and review streamlines, pressure fields, forces, and coefficients in the browser.
What file types can I upload?
The source shows support for STL, OBJ, STEP, IGES, GLB, and FBX uploads. The model appears in an in-browser WebGL viewer before simulation.
Is there a free version?
Yes. The site says new accounts include 5 free demo simulations and no card is required to start. It also lists paid options for saving results, using your own API key and OpenFOAM worker, or running managed solves.
Can I export or compare simulation results?
The rendered workflow includes exporting engineering results to CSV and PDF, and the comparison tool lets you review two runs side by side.
Does Ventorah support team or enterprise setup?
The site provides browser sign-in, account creation, and dashboard settings for connecting an Anthropic API key. It does not show a public pricing page or detailed team plan information in the collected sources.
