Team presentation

OPALE has several objectives : analyze mathematically single or multi-disciplinary coupled systems of partial differential equations arising from physics or engineering in view of their optimization or control ( geometrical optimization); contruct and experiment efficient numerical approximation methods (coupling algorithms, model reduction) and optimization algorithms (gradient-based and/or evolutionary algorithms, game theory); develop software platforms for the distributed parallel computation of the related discrete systems. Application problems include multi-disciplinary optimum shape design of an aircraft wing (in collaboration with Dassault Aviation), functional optimization of a rocket system (in collaboration with CNES), and optimization of antenna systems (in collaboration with France Télécom). OPALE also has a strong implication in several European networks involved in aspects of code validation.
