Towards high-Fidelity Aero-Structural Simulation - Theoretical Challenges And Practical Solutions

Event organized by: 3AF Aerodynamics & Structures Technical Commissions / ONERA – ISAE SUPAERO


The aim of this joint scientific and technical day organized by the 3AF Aerodynamics and Structures Technical Committees is to review the state of the art in high-fidelity digital aerostructural simulation, i.e. coupled fluid- structure simulation, in industry and research laboratories in the aerospace and defense sectors
