Project Falcon is a free* technology preview that simulates air flow around vehicles, buildings, outdoor equipment, consumer products, or other objects of your choosing in a virtual wind tunnel.
Falcon technology is extremely geometry tolerant and easy to use, enabling you to begin seeing and understanding air flow behaviour within seconds of starting the application. Results update almost in real-time in response to changes in wind-direction and speed that you specify. Visualization tools available within the Falcon family of applications include 2D and 3D flow lines, shaded result planes, vector plots, and surface pressure shading. Quantified outputs include velocity, pressure, drag force, and drag coefficient. Project Falcon uses a revolutionary automatic meshing technology that can handle flow around any geometry at any stage of design. This technology is coupled with a transient, incompressible fluid flow solver and LES turbulence model in a way that delivers quick results and requires very little setup on behalf of the user.
Project Falcon is available as follows:
