Title: Domain Decomposition Boundary Element Methods: Preprocessing and Parallel Solution
Abstract: SummaryThe Domain Decomposition Method (DD) is a powerful tool for deriving boundary element equations approximating boundary value problems with piecewise homogeneous material properties and for constructing the corresponding parallel solvers. Although the method allows the coupling of different discretization techniques, i.e., Boundary Element Methods (BEM) and Finite Element Methods (FEM), as it is desired in various applications, we discuss pure BEM formulations in this paper. We introduce the Adaptive Domain Decomposition Preprocessor ADDPre which realizes an automatic decomposition of the domain under consideration into p subdomains, where p is the number of processors to be used. Furthermore, the parallel algorithm and the preconditioners being involved are discussed. Numerical examples, including potential and linear elasticity problems, which demonstrate the high efficiency of the algorithm are presented.
