A Domain Decomposition Method for Hybrid Shell Vector Element with Boundary Integral Method

Hybrid Finite Element Boundary Integral Method

MKT0000528 › With recent improvements in the efficiency of integral equation solutions it is now possible to combine the integral equation procedure with the finite element method (FEM) in a hybrid Finite Element Boundary Integral approach (FEBI) [1]. In electromagnetics the FEM is a general purpose technique that solves for volumetric electric fields and can be used to accurately characterize ...

A Domain Decomposition Method Combining a Boundary Element Method with a Meshless Local Petrov-Galerkin Method

A non-overlapping domain decomposition algorithm combining boundary element method with meshless local Petrov-Galerkin method is presented for solving the boundary value problem with discontinuous coefficient in this paper. The static relaxation parameter is employed to speed up the convergence rate. The convergence range and the optimal value of static relaxation parameter are studied, but the...

A Domain Decomposition of the Finite-Element Boundary-Integral Method for Finite Array Analysis

An extension of the FE-BI method for the analysis of finite arrays is presented. The method takes advantage of the structural redundancies of repeated array elements and coupling paths within the array to achieve significant CPU and storage savings. The method is presented and discussed along with results and comparisons to traditional approaches.

Coupling of a non-overlapping domain decomposition method for a nodal Finite Element Method with a Boundary Element Method

Non-overlapping domain decomposition techniques are used both to solve the finite element equations and to couple them with a boundary element method. A suitable approach dealing with finite element nodes common to more than two subdomains, the so-called cross-points, endows the method with the following advantages. It yields a robust and efficient procedure to solve the equations resulting fro...
