Multilevel Parametrization for Aerodynamical Optimization of 3D Shapes
Résumé
We introduce and discuss a combination of methods and options that aim at the aerodynamical optimization of a flow around an arbitrary aircraft shape. The flow is governed by the Euler equations, discretized by a Mixed Element-Volume method on a fixed unstructured tetrahedrization. The shape parametrization relies on the skin of the above mesh through a hierarchical representation. Descent-type and One-Shot algorithms are devised and adapted to the solution of a few model problems.
