elsA

Le code elsA est un ensemble logiciel développé par l'Onera pour la simulation des écoulements complexes externes et internes et pour les applications multi-disciplinaires mettant en jeu l'aérodynamique. Ceci inclut les disciplines et aspects suivants :

• Aerodynamics, aeroelasticity, aerothermics coupling, aeroacoustics coupling
• Aircrafts, helicopters, turbomachinery, missiles, launchers, air intakes, nozzles, propulsive jets
• Research and industrial applications
• Euler, RANS, URANS, DES, LES simulations
• Mono-species perfect gas assumption with a user-given value of the specific heat ratio (equilibrium real gas assumption in development)
• Calculation of sensitivities for optimum design

Ses atouts et fonctionnalités sont les suivants:

• skills in physics modelizations and numerical methods on subjects such as ALE, chimera scheme, dual time stepping, implicit acceleration, low velocities, moving frames, multigrid acceleration, turbulence modeling, ...
• in-depth knowledge of physical phenomena occuring in various application domains such as aircraft, helicopter, turbomachinery, ...
• use of modern and rigorous methods for software production in such matters as software architecture, design method, interface architecture, software engineering, configuration management, development validation, project management, quality assurance, customer support, developer support, documentation, ...

Ses utilisateurs sont notamment Airbus, le CEA, le groupe Safran (Snecma, Turbomeca, Techspace Aero, Teuchos), Eurocopter, MBDA, le Cnes ou encore GIAT.
