Nowadays, analytical aerodynamic studies have become increasingly popular and important to understand how a vehicle should behave in real life. Depending on the type of car being studied, the focus is on different factors, such as downforce or drag or aerodynamic efficiency. In general, the most important topic for road vehicle is to reduce the fuel consumption while, for racing car, the focus is also on the contribution of downforce, depending on the type of racetrack. In order to reduce design processing time, the use of aerodynamic software to simulate aerodynamic behavior and replace experimental studies in the early development phase has become widespread in recent years.
