Run a virtual wind tunnel on any 3D model — right in your browser.
Upload STL, OBJ, STEP or GLB. Set your flow conditions. Watch streamlines, pressure fields and wake form in real time — then read off lift, drag and moment coefficients. Or run it thermal: surface-temperature hotspots, Nusselt and heat-transfer, painted on the part. No install, no license server.
New · Mould design
Injection mould design, straight from your 3D file
Upload a plastic part and get a complete injection-mould concept in seconds — worked out by the same rules a toolmaker uses, and cut as real steel you can open in CAD.
- Pull direction, parting line, undercuts and side actions (sliders, lifters)
- Cavity layout, gates and a flow-balanced runner — cold, three-plate or hot runner
- Cooling circuits, ejector pins and sleeves, vents and cold-slug wells
- Clamp tonnage, cycle time, tool steel and a feasibility check that the tool can run
- Download the cavity and core inserts and every plate as STL
Free on four sample parts · upload your own on Pro · a concept to review with your toolmaker, not a substitute for a full mould-flow analysis.
Everything an aero study needs
A complete pre/solve/post workflow, tuned for aerospace, automotive and drone aerodynamics.
In-browser 3D viewer
STL / OBJ / GLB render instantly with orbit, wireframe, transparent and bounding-box modes plus measurement tools.
Virtual wind tunnel
Streamlines, velocity vectors, pressure & velocity contours, vorticity, wake and flow separation — animated live.
Thermal simulation
Heated-body buoyant CFD: hold a surface temperature or dissipate a heat flux, then read Nusselt, h and a surface-temperature hotspot map painted right on the part.
Full flow setup
Speed, direction, density, temperature, pressure, humidity, altitude, fluid and turbulence model — all configurable.
Engineering results
Cl, Cd, Cm, Reynolds, Mach, 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
Put two runs side by side, overlay pressure and airflow, and read a performance difference table.
AI aero assistant
Ask why drag is high or how to add lift. Get flow-separation explanations and design recommendations.
Validated OpenFOAM backend
Parallel snappyHexMesh + simpleFoam in Docker, benchmarked against published wind-tunnel data — sphere drag within ~10% of experiment.
Four steps to a full report
Upload geometry
Drop an STL, OBJ, STEP, IGES, GLB or FBX. It appears in the WebGL viewer immediately.
Configure the tunnel
Dial in wind speed, direction, fluid and turbulence model, then pick a mesh resolution.
Run the solve
The solver meshes, iterates to convergence and streams residuals back as it runs.
Read & export
Inspect coefficients, charts and flow fields — export CSV or a PDF report.
Example simulations
Representative runs across domains — including a real parallel OpenFOAM solve validated against published wind-tunnel data.
