چکیده

Shape optimization aims to optimize an objective function by changing the shape of 10 the computational domain. In recent years, shape optimization has received consid11 erable attentions. On the theoretical side there are several publications dealing with 12 the existence of solution and the sensitivity analysis of the problem; see e.g., [6] and 13 references therein. On the practical side, optimal shape design has played an impor14 tant role in many industrial applications, for example, aerodynamic shape design [7], 15 artery bypass design [1, 10], and so on. In this paper, we propose a general frame16 work for the parallel solution of shape optimization problems, and study it in detail 17 for the optimization of an artery bypass problem. 18

Elliptic variational inequalities with multiple bodies are considered. It is assumed 7 that an active set method is used to handle the nonlinearity of the inequality constraint, which 8 results in auxiliary linear problems. We describe two domain decomposition methods for solv9 ing such linear problems, namely, the FETI-FETI (finite element tearing and interconnecting) 10 and hybrid methods, wh...

The usual setting of an eddy current problem distinguishes between a conduct7 ing region and an air region (non-conducting) surrounding the conductor. For the numerical 8 approximation of this heterogeneous problem it is very natural to use iterative substructur9 ing methods based on transmission conditions at the interface. We analyze the convergence 10 of the Dirichlet-Neumann iterative metho...

In this paper we present a stable boundary element tearing and interconnecting 6 domain decomposition method for the parallel solution of the electromagnetic wave equation 7 with piecewise constant wave numbers. In particular we consider stable boundary integral 8 formulations and generalized Robin type transmission conditions to ensure unique solvability 9 of the local subproblems. Numerical r...
