چکیده
1. Abstract In this contribution an innovative method for shape optimization with parametrization directly on FE mesh is proposed. The major shortcomings of CAD-free parametrization are discussed and global filter techniques are presented in this context. A global filter for shape optimization with FE-parametrization is developed and applied to numerical examples of basic shapes. The influence of locking phenomena in the context of shape optimization is discussed. Finally a local filter for bead optimization is proposed. 2.

A Dynamic Parametrization Scheme for Shape Optimization Using Quasi-Newton Methods
A variable parametrization scheme is developed and demonstrated for shape optimization using quasi-Newton methods. The scheme performs adaptive parametrization refinement while preserving the approximate Hessian of the shape optimization problem and enables free-form shape design using quasi-Newton optimization methods. Using a Bspline parametrization, the scheme is validated using a 1-D shape ...

In this paper we present a new approach for shape optimization that combines two different types of model reduction: a suitable low-dimensional parametrization of the geometry (yielding a geometrical reduction) combined with reduced basis methods (yielding a reduction of computational complexity). More precisely, free-form deformation techniques are introduced for the geometry description and i...

Optimal control and shape optimization problems governed by partial differential equations (PDEs) arise in many applications involving computational fluid dynamics; they can be seen as many-query problems since they involve repetitive evaluations of outputs expressed as functionals of field variables. Since they usually require big computational efforts, looking for computational efficiency in ...
