Abstract
A new approach for optimal shape design based on a CAD-free framework for shape and unstructured mesh deformations, automatic differentiatio n for the gradient computation and mesh adaption by metric control is presented. The CAD-free framework is shown to be particularly convenie nt for optimization when the mesh connectivities and control space siz e are variable during optimization. Constrained optimizations for subs onic, transonic and supersonic regimes have been investigated.
