Online aerodynamics tool for engineers and designers. Test and improve on aerodynamic efficiency of 3D models. Analyse drag, lift, downforce and noise.

Simulation data: download the full simulation data and process the results in paraview – see this video. You can analyze every small detail in the flow by creating your own streamlines, pressure maps, and so on.

If you’re just exploring initial concepts or simple shapes, a concept simulation will do. If you’re working on the final details or a very complex 3D model, our ultimate simulation is the best choice. Give the project a name and simply drag & drop your 3D file into AirShaper.

Based on input parameters like rolling resistance, air drag, masses and inertias, gearbox friction, auxiliary power and engine performance, it simulates fuel consumption and CO2 emissions based on standardised driving cycles.

The only solution for the latter is to include the full wind tunnel into the virtual CFD simulation. In this blog, we'll compare the physical wind tunnel test with a CFD simulation applied on a high-quality exterior of the Tesla Model Y.

The coefficient of drag is a common metric used in aerodynamics. But what does it mean, how can you measure it, and how can you use it to optimise aerodynamic performance? The definition of drag. The Drag Coefficient Cd quantifies the resistance of an object relative to its frontal area as it moves through a fluid.

We reveal the aerodynamic secrets behind the Tesla Cybertruck. Using a public 3D model and AirShaper software to run CFD simulations, we calculate the Cybertruck’s drag coefficient.

----- The AirShaper videos cover the basics of aerodynamics (aerodynamic drag, drag & lift coefficients, boundary layer theory, flow separation, reynolds number...), simulation aspects (computational fluid dynamics, CFD meshing, ...) and aerodynamic testing (wind tunnel testing, flow visualization, ...).

Analyze drag & lift forces as well as pitch & yaw moments to improve efficiency, range, comfort and handling. Optimize the shape of fenders, windscreen, cooling inlets and more to reduce drag and improve performance. Use 3D flow visualizations to understand & improve modifications to bodywork or even design a completely new body.

Another way to visualise drag is to use 3D pressure clouds. These are areas with a pressure lower than the local surrounding air and highlight which features generate drag. From the images below, we can clearly see that the large open wheel arches are a major source of drag.
