Basically, design is generated from concept or styling work, then the engineering design is produced. Engineering design can be produced based on many requirements and informations, such as design concept and technical specification and requirements. These 3D design can be generated using softwares such as CATIA, SolidWorks and many others.
After that, Finite Element (FE) analysis is performed to verify the design reliability in terms of strength, vibration, Computational Fluid Dynamcis (CFD) and many others. Similarly, techncial requirements and specifications are required to complete a simulations for a high accuracy percentage. Softwares and simulation applications are used to perform the analysis, such as using ABAQUS and Hyperworks.
