The accuracy of a finite element numerical approximation of the solution of a partial differential equation can be spoiled significantly by singularities. This phenomenon is especially critical for high order methods. In this paper, we show that, if the PDE is linear and the singular basis functions

The aim of the paper is to study the capabilities of the extended finite element method (XFEM) to achieve accurate computations in non-smooth situations such as crack problems. Although the XFEM method ensures a weaker error than classical finite element methods, the rate of convergence is not impro
## Abstract Although unconditionally stable (US), the accuracy of ADIβFDTD is not so high as that of conventional FDTD. In this paper, a highβorder USβFDTD based on the weighted finiteβdifference method is presented. A strict analysis of stability shows that it is unconditionally stable. And, more
We establish optimal (up to arbitrary Ξ΅ > 0) convergence rates for a finite element formulation of a model second order elliptic boundary value problem in a weighted H 2 Sobolev space with 5th degree Argyris elements. This formulation arises while generalizing to the case of non-smooth domains an un
