Hierarchical hp Finite Elements inHybrid
In this paper we introduce a new set of hp nite element expansions for use in hybrid domains using hexahedrons, prisms, pyramids and tetrahedrons. The expansions are explained in terms of a uniied notation which incorporates the standard hexahedral hp nite element expansion. The new bases are motivated from a set of orthogonal polynomial expansions within each of the hybrid domains. The polynom...
متن کاملDomain Decomposition and hp-Adaptive Finite Elements
In this work, we report on an ongoing project to implement an hp-adaptive finite element method. The inspiration of this work came from the development of certain a posteriori error estimates for high order finite elements based on superconvergence Bank and Xu [2003a,b], Bank et al. [2007]. We wanted to create an environment where these estimates could be evaluated in terms of their ability to ...
متن کاملhp - Finite Elements for Elliptic Eigenvalue Problems
Convergence rates for finite element discretisations of elliptic eigenvalue problems in the literature usually are of the form: If the mesh width h is fine enough then the eigenvalues resp. eigenfunctions converge at some well-defined rate. In this paper, we will determine the maximal mesh width h0 — more precisely the minimal dimension of a finite element space — so that the asymptotic converg...
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 ...

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.
