Abstract
The aim of the paper is to present a fast and robust method for computing turbulent viscous flows around complex geometries. A single unstructured mesh made of general polygonal elements is obtained by intersecting hyperbolic grids generated in the boundary layers and in the wakes with a Cartesian grid covering the whole domain of computation. The flow solver is based on a cell-centered high-order finite volume scheme. A multigrid preconditioned Newton-Krylov method is used to obtain steady-state solutions.
