The Automatic Aerodynamic CFD Framework Employing Vehicle Specifications at the Concept Stage of Development

This paper describes tool development with which makes it possible for vehicle stylists and aerodynamicists to easily use Computational Fluid Dynamics, i.e., CFD, and evaluate aerodynamic performance at the concept stage of car development. This tool automatically provides CFD results to the user by preparing the vehicle exterior geometries and car specifications. The vehicle exterior, floor, and tires are the essential geometry data. This tool automatically generates the floor and tires based on the vehicle specifications. It, thereafter, executes the following process: automatic mesh generation, solver settings, calculations and standard post-processing. The user is able to obtain results within two hours. The tool enables stylists and aerodynamicists to understand flow phenomena in a timely fashion.
