The design process of electric vehicle aerodynamic parts is a specific challenge for engineers, especially in automation of such design tasks case. Classical techniques of the design process automation such as simple model parametrization become not sufficient for the surface modelling techniques. Furthermore, validation of every implemented changes into the model forces the need for special CFD (Computational Fluid Dynamics) software application. Such approach requires data transfer between usually two or more different kinds of methods supported by different advanced software. Any model changes are based on subjective CFD analysis results interpretation. In this paper, authors show a novel approach to design of electric vehicle aerodynamic parts using specially developed distributed system that combines CAD, CFD and additional optimization control software. The main task of the proposed system is automatic generation of elements optimal from the aerodynamics point of view. The main issue in such case is proper distribution of different design tasks between different kinds of software performing their tasks on the basis of advanced methods. Proper data transfer and complex mathematical description of parametrised surfaces is necessary to control such process of optimization in proper way. Mathematical approach allows for parametrization and optimization of generated surfaces. All of those problems with proposition of the distributed optimisation system are indicated and described in the paper.
