Sažetak
Car is designed using the software package Autodesk 3ds Max. Polygonal modeling method was used and designed car represent a new conceptual solution car design. After modeling a car in mentioned software, final digital images are generated too. Final digital images are generated using the Mental Ray rendering tool as a default rendering tool of Autodesk 3ds Max. Attention is given only to the external design of the car, while the interior is not modeled. Furthermore, using the software ANSYS Fluent, 2D simulation of the airflow around the side contour of the vehicle was made in purpose of making changes in the geometry of the vehicle to improve the design in terms of reducing air resistance and improving aerodynamics. Most attention of that is given in changing value of angle between the hood and front windshield of car, and analysing back of the car with and without the rear wing. Leading to the obtained 2D simulation and leading with modifications of initial 2D model, existing 3D car model is redesigned. Assumption is that new 3D car model is resulting with better aerodynamic properties. 3D analysis of redesigned car model in terms of mentioned changes is performed too in order to analyse possible improvements compared to the initial design.
