This thesis investigates the development and analysis of an alternative meshing methodology for Computational Fluid Dynamics (CFD) simulations, focusing on the comparison between meshes generated by ANSA and STAR-CCM+ software. The study is applied to the single-seater car designed by “Squadra Corse PoliTo” for the Formula SAE international university competition. The primary objective is to generate a high-quality mesh in ANSA and rigorously evaluate it against the STAR-CCM+ mesh using various quality criteria, such as element skewness, face validity, and overall mesh structure. In addition, this new mesh is validated through a series of CFD simulations conducted using the ANSA mesh as a discretization of the computational domain.
