Parallel Coupling of FEM and BEM for 3D Elasticity Problems,e simple and efficient method of Farhat [4]. To obtain the BE Schur complement matrices, one has to solve a Neumann boundary value problem in each BE subdomain locally. The BE discretization results in a linear system, where the solution is increasingly sensitive to perturbations (e g roundoff error

Efficient Calculation of Acoustic Fields by Boundary Element Method,be derived by combining the hydrodynamic equations of motion and the local mass balance, the continuity equation. In order to obtain a linearized form of the resulting equations, all the physical quantities and their spatial derivatives are considered to be small variations of their undisturbed posi

On the Efficient Realization of Sparse Matrix Techniques for Integral Equations with Focus on Panel is applied transforming the PDE on a domain . into an integral equation defined on the boundary of .. This integral equation can be discretized by Petrov-Galerkin methods defined on the surface of .. Instead of the discretization of the whole domain, only the lower dimensional boundary of . has to
