This work concerns the development of the "N.E.S" code that solves the full 3D Reynolds averaged Navier-Stokes equations in an engineering environment. A multiblock/multiface technique well adapted for parallel computations has been implemented. For realistic estimates of aerodynamic coefficients a low dissipation numerical method is used combining the high accuracy ENO scheme of Harten in a multigrid framework with a defect correction for robust speed-up.
