An Adaptive Nite Element Technique with A-priori Mesh Grading
نویسنده
چکیده
In this paper we discuss a combined a-priori a-posteriori approach to mesh reenement in nite element methods for two-and three-dimensional elliptic boundary value problems containing boundary singularities. We review rst both techniques of a-priori mesh grading around singularities and a-posteriori mesh reenement controlled by local error indicators. In examples of two-and three-dimensional boundary value problems we demonstrate the applicability and eeciency of various combined mesh reenement strategies.

Coupling of Non - Conform Fem and Bem
This paper is concerned with the coupling of non-conform nite element and boundary element methods in continuation of Part I (C. Carstensen, S.A. Funken: Coupling of non-conform nite elements and boundary elements I: a priori estimates), where we recast the interface model problem, introduced a coupling scheme and proved a priori error estimates. In this paper, we establish sharp a posteriori e...
متن کاملCoupling of Mixed Finite Elements and Boundary Elements
The symmetric coupling of mixed nite element and boundary element methods is analysed for a model interface problem with the Laplacian. The coupling involves a further continuous ansatz function on the interface to link the discontinuous displacement eld to the necessarily continuous boundary ansatz function. Quasi-optimal a priori error estimates and sharp a posteriori error estimates are esta...

The nite element method with anisotropic mesh grading for elliptic problems in domains with corners and edges Abstract. This paper is concerned with a speciic nite element strategy for solving elliptic boundary value problems in domains with corners and edges. First, the anisotropic singular behaviour of the solution is described. Then the nite element method with anisotropic, graded meshes and...
متن کاملAdaptive Recovery of near Optimal Meshes in the Finite Element Method for Parameter Dependent Problems
A method for adaptive construction of nearly optimal nite element meshes is presented. The method is based on the notion of mesh density. For parametrized problems optimal meshes for new parameter values can be predicted from previous meshes. The method is of the one shot type, normally giving a suuciently good approiximation to the optimal mesh in the rst attempt , but when the rst shot is uns...
