dc.description.abstract
We consider PDE constrained shape optimization in the frame- work of finite element discretization of the underlying boundary valu e problem. Our approach employs (i) B-spline based representations of the deformation diffeomorphism, and (ii) superconvergent domain integral expressions for the shape gradient. We study the balance of the discretization errors of the finite element method and the B-sp line approximation. We provide numerical evidence of the performance of this method on a test case stemming from the class of exterior Bernoulli free boundary problems.
