摘要
Early design of automotive products, stylists who designed the new car styling were not based on the Aerodynamic theory. Therefore, the new styling often has larger drag coefficient, without considering the Aerodynamic performance. To deal with this question, an advanced Aerodynamic optimization method was used to solve the problem. The CFD engineers can run this optimization so quickly to find out the right optimization direction in an early design phase and will deliver a first design proposal to the styling designer.
