JAGUAR: a New CFD Code Dedicated to Massively Parallel High-Order LES Computations on Complex Geometry

Abstract

International audienceLES of industrial flows is associated with geometrical complexity and requires high order schemes to minimize dissipation and dispersion. To tackle these two issues it is necessary to use unstructured grids and High Performance Computing algorithms. In this context, CERFACS initiated two years ago the development of a new CFD code called JAGUAR based on a mathematical framework leading to high-level capability for LES. In this paper, many topics for HPC are introduced and solved in order to obtain the best code performance
