Hanging nodes and XFEM

International Journal for Numerical Methods in Engineering, 2010
AbstractThis paper investigates two approaches for the handling of hanging nodes in the framework of extended finite element methods (XFEM). Allowing for hanging nodes, locally refined meshes may be easily generated to improve the resolution of general, i.e. model‐independent, steep gradients in the problem under consideration.

EFFICIENT METHODOLOGIES TO HANDLE HANGING PAGES USING VIRTUAL NODE

Cybernetics and Systems, 2011
In this article we first explain the knowledge extraction KE process from the World Wide Web WWW using search engines. Then we explore the PageRank algorithm of Google search engine a well-known link-based search engine with its hidden Markov analysis. We also explore one of the problems of link-based ranking algorithms called hanging pages or dangling

Adaptation for hybrid unstructured grid with hanging node method

15th AIAA Computational Fluid Dynamics Conference, 2001
The unstructured grid technology is a promising approach since it provides the ability to automatically adapt grid points where required by flow physics, hence optimizing computational cost with respect to accuracy. This paper presents an adaptation scheme for refining and coarsening hybrid unstructured grids based on evolving flow field data using a ...

Diagnosing hang‐ups and automatic restoration for nodes in networks of ring topology

Electronics and Communications in Japan (Part I: Communications), 1990
AbstractThis paper proposes a method to diagnose and restore automatically hang‐ups at the nodes connected into networks of ring topology and afterward reports the place where the hang‐ups occurred to an arbitrary equipment. Various measures have been taken to prevent hang‐ups from occurring at the nodes.

Adaptive $hp$-FEM with Arbitrary-Level Hanging Nodes for Maxwell's Equations

Advances in Applied Mathematics and Mechanics, 2019
Adaptive higher-order finite element methods ($hp$-FEM) are well known for their potential of exceptionally fast (exponential) convergence. However, most $hp$-FEM codes remain in an academic setting due to an extreme algorithmic complexity of $hp$-adaptivity algorithms.

Adaptive Quadrilateral and Hexahedral Finite Element Methods with Hanging Nodes and Convergence Analysis

Journal of Computational Mathematics, 2010
In this paper we study the convergence of adaptive finite element methods for the general non-affine equivalent quadrilateral and hexahedral elements on 1-irregular meshes with hanging nodes.

Fully Computable Error Bounds for Discontinuous Galerkin Finite Element Approximations on Meshes with an Arbitrary Number of Levels of Hanging Nodes

SIAM Journal on Numerical Analysis, 2010
We obtain fully computable a posteriori error bounds on the broken energy seminorm and discontinuous Galerkin norm (DG-norm) of the error in first order symmetric interior penalty Galerkin (SIPG), nonsymmetric interior penalty Galerkin (NIPG), and incomplete interior penalty Galerkin (IIPG) finite element approximations of a linear second order ...
