Fluid Mechanics, Finite Elements, and Supercomputers 870563

Computational fluid dynamics has long been the realm of finite difference and finite volume techniques although the use of finite element techniques in structural and solid mechanics applications in industry is now widespread and well established. This paper will address the relative merits and use of numerical simulation, in particular finite elements, in fluid mechanics in the context of the automotive industry and the role of the supercomputer in the simulation of realistic problems. The turbulent calculation of airflow around a car body using a finite element program will be presented.
