چکیده
In this paper, the artificial boundary method for Poisson problem in an infinite domain with a concave angle is investigated. The exact and approximate elliptical arc artificial boundary conditions are given. The finite element approximation is formulated in a bounded domain using the approximate artificial boundary condition and error estimates are obtained. Finally, some numerical examples show the effectiveness of this method.

An Iteration Method using Elliptical Arc Artificial Boundary for Exterior Problems
In this paper, an iteration method using elliptical arc artificial boundary is designed to solve exterior Poisson problem with a concave angle. It is shown that the iteration method is equivalent to a Schwarz alternating method. The convergence of this method is given. The convergence rate is analyzed in details for a typical domain. Finally, some numerical examples are given, which show the ef...
متن کاملLocal absorbing boundary conditions for elliptical shaped boundaries
We compare several local absorbing boundary conditions for solving the Helmholtz equation, by a finite difference or finite element method, exterior to a general scatterer. These boundary conditions are imposed on an artificial elliptical or prolate spheroid outer surface. In order to compare the computational solution with an analytical solution, we consider, as an example, scattering about an...
متن کاملA Boundary Integral Equation for Deformations of an Elastic Body with an Arc Crack*
A solution for a class of two-dimensional elasticity problems concerning an isotropic body with an arc crack in its interior is obtained in terms of an integral taken around the exterior boundary of the body. A numerical procedure for solving this integral equation is outlined and numerical results for a test problem are given.
متن کاملExact Non-Reflecting Boundary Conditions on Perturbed Domains and hp-Finite Elements
For exterior scattering problems one of the chief difficulties arises from the unbounded nature of the problem domain. Inhomogeneous obstacles may require a volumetric discretization, such as the Finite Element Method (FEM), and for this approach to be feasible the exterior domain must be truncated and an appropriate condition enforced at the far, artificial, boundary. An exact, non-reflecting ...
