# EURANUS

The engineering of multiblock/multigrid software for Navier--Stokes flows on structured meshes The paper describes EURANUS -- a general software system for the simulation of 3-D Reynolds-averaged Navier-Stokes flows about complex geometries, being developed for the European Space Agency. The software treats either perfect gases or air in chemical equilibrium. Closure of the Reynolds stresses is provided by either the Baldwin-Lomax turbulence model, or the $kappa-varepsilon$ model. The key to a successful multiblock code, particularly if it is to serve as an evolving platform, lies in the design of a suitable data structure and a concept for the management of the data. Two computed examples of viscous laminar hypersonic flow around the HERMES spaceplane provide an initial demonstration of the code.
