Multi-level hp-adaptivity and explicit error estimation
Correspondence: [email protected] Chair for Computation in Engineering, Technische Universität München, Arcisstraße 21, 80333 München, Germany Full list of author information is available at the end of the article Abstract Recently, a multi-level hp-version of the Finite Element Method (FEM) was proposed to ease the difficulties of treating hanging nodes, while providing full hp-approximat...
متن کاملVerification of Goal-oriented Hp-adaptivity
The paper presents calculations for the radiation of a loop antenna wrapped around a metallic cylinder into a conductive medium. The problem has been solved analytically by using Fourier transform and Bessel functions. The evaluation of the analytical solution, involves the use of exponentially scaled Bessel functions, and FFT to evaluate inverse Fourier transform, with all computations done in...

15 صفحه اولGoal - Oriented Error Estimation and Adaptivity for theFinite Element
In this paper, we study a new approach in a posteriori error estimation, in which the numerical error of nite element approximations is estimated in terms of quantities of interest rather than the classical energy norm. These so-called quantities of interest are characterized by linear functionals on the space of functions to where the solution belongs. We present here the theory with respect t...
متن کاملDuality-based adaptivity in the hp-finite element method
In this paper a duality-based a posteriori error analysis is developed for the conforming hp Galerkin finite element approximation of second-order elliptic problems. Duality arguments combined with Galerkin orthogonalty yield representations of the error in arbitrary quantities of interest. From these error estimates, criteria are derived for the simultaneous adaptation of the mesh size h and t...
