CFD Tunnel — a virtual wind tunnel in your browser CFD Tunnel is a browser-based aerodynamic CFD tool. You upload a 3D model or pick a built-in shape, choose a wind speed, and it solves the airflow with a real OpenFOAM simulation and reports the drag coefficient (Cd), lift, downforce, centre of pressure, and Reynolds number. No install, no workstation, nothing to set up. Pricing

Free Beta — $0/month. 5 simulations a month, built-in reference shapes, the fast in-browser solver, and interactive 3D streamlines.

Premium Lite — $8/month or $80/year. 20 simulations a month, upload your own CAD (.stl / .obj), the real OpenFOAM solver, drag and lift and aero balance, a rolling road for ground vehicles, saved run history, and a PDF study report for every run.

Premium Pro — $19/month or $190/year. 50 simulations a month, high-fidelity solves, a choice of turbulence models, and automated angle and speed sweeps.
