Overnight Industrial LES for External Aerodynamics

Abstract

This paper summarizes the efforts carried out over the last year to achieve overnight industrial Large-Eddy Simulation (LES) runs for external car aerodynamics. The solver employed is based on adaptive cartesian blocks, uses explicit timestepping to advance the Navier-Stokes equations describing mildly compressible flows, and scales well to tens of thousands of cores. The capabilities developed to date are tested on a Volkswagen Golf.
