“CleanUp: Improving Quadrilateral Finite Element Meshes”
Unless an all quadrilateral (quad) finite element mesher is of a high quality, the mesh it produces can contain misshapen quads. This paper will describe “CleanUp”, written to improve an all quad mesh. CleanUp looks at improving node connectivity, boundary and flange patterns, quad shape, and to some extent, quad size. CleanUp is currently used in conjunction with the Paver algorithm developed ...
متن کاملConvergence of an adaptive finite element method on quadrilateral meshes
We prove convergence and optimal complexity of an adaptive finite element algorithm on quadrilateral meshes. The local mesh refinement algorithm is based on regular subdivision of marked cells, leading to meshes with hanging nodes. In order to avoid multiple layers of these, a simple rule is defined, which leads to additional refinement. We prove an estimate for the complexity of this refinemen...
متن کاملThe Patch Recovery for Finite Element Approximation of Elasticity Problems under Quadrilateral Meshes
In this paper, some patch recovery methods are proposed and analyzed for finite element approximation of elasticity problems using quadrilateral meshes. Under a mild mesh condition, superconvergence results are established for the recovered stress tensors. Consequently, a posteriori error estimators based on the recovered stress tensors are asymptotically exact.
متن کاملQuadrilateral and Hexahedral Element Meshes
This chapter explains techniques for the generation of quadrilateral and hexahedral element meshes. Since structured meshes are discussed in detail in other parts of this volume, we focus on the generation of unstructured meshes, with special attention paid to the 3D case. Quadrilateral or hexahedral element meshes are the meshes of choice for many applications, a fact that can be explained emp...
متن کاملAdaptive Refinement of Quadrilateral Finite Element Meshes Based on MSC.Nastran Error Measures
This paper describes and demonstrates a process for adaptive refinement of quadrilateral curved shell meshes using error estimates from MSC.Nastran. The meshes have been generated originally using Unigraphics'(UG) Scenario application. Although refinement procedures for finite element meshes have been in use for many years, automated procedures have most generally been developed for triangular ...
