Book Synopsis Finite Element Mesh Generation by : Daniel S.H. Lo
Download or read book Finite Element Mesh Generation written by Daniel S.H. Lo. This book was released on 2015-01-15. Available in PDF, EPUB and Kindle. Book excerpt: Highlights the Progression of Meshing Technologies and Their Applications Finite Element Mesh Generation provides a concise and comprehensive guide to the application of finite element mesh generation over 2D domains, curved surfaces, and 3D space. Organised according to the geometry and dimension of the problem domains, it develops from the basic meshing algorithms to the most advanced schemes to deal with problems with specific requirements such as boundary conformity, adaptive and anisotropic elements, shape qualities, and mesh optimization. It sets out the fundamentals of popular techniques, including: Delaunay triangulation Advancing-front (ADF) approach Quadtree/Octree techniques Refinement and optimization-based strategies From the geometrical and the topological aspects and their associated operations and inter-relationships, each approach is vividly described and illustrated with examples. Beyond the algorithms, the book also explores the practice of using metric tensor and surface curvatures for generating anisotropic meshes on parametric space. It presents results from research including 3D anisotropic meshing, mesh generation over unbounded domains, meshing by means of intersection, re-meshing by Delaunay-ADF approach, mesh refinement and optimization, generation of hexahedral meshes, and large scale and parallel meshing, along with innovative unpublished meshing methods. The author provides illustrations of major meshing algorithms, pseudo codes, and programming codes in C++ or FORTRAN. Geared toward research centers, universities, and engineering companies, Finite Element Mesh Generation describes mesh generation methods and fundamental techniques, and also serves as a valuable reference for laymen and experts alike.

Book Synopsis Mesh Generation and Adaptation by : Rubén Sevilla
Download or read book Mesh Generation and Adaptation written by Rubén Sevilla. This book was released on 2022-05-18. Available in PDF, EPUB and Kindle. Book excerpt: The developments in mesh generation are usually driven by the needs of new applications and/or novel algorithms. The last decade has seen a renewed interest in mesh generation and adaptation by the computational engineering community, due to the challenges introduced by complex industrial problems.Another common challenge is the need to handle complex geometries. Nowadays, it is becoming obvious that geometry should be persistent throughout the whole simulation process. Several methodologies that can carry the geometric information throughout the simulation stage are available, but due to the novelty of these methods, the generation of suitable meshes for these techniques is still the main obstacle for the industrial uptake of this technology.This book will cover different aspects of mesh generation and adaptation, with particular emphasis on cutting-edge mesh generation techniques for advanced discretisation methods and complex geometries.

Book Synopsis Research and application of adaptive finite element Mesh generation by : Ju-Lin Shan
Download or read book Research and application of adaptive finite element Mesh generation written by Ju-Lin Shan. This book was released on 2007. Available in PDF, EPUB and Kindle. Book excerpt: An improved adaptive triangle and tetrahedral adaptive mesh generator has been developed. The interfaces of B-Rep which is used to smooth over the differences in various CAD systems and the mesh data structures based on topology and relation matrix are also introduced. For 3D combined surfaces, an extended Advancing Front Technique (AFT) is extended to overcome the meh quality-worsening problem in closed surface mesh generation due to introducing virtual boundaries into 2D open parametric domains in resulting generate high-quality meshes and guarantee convergence in both open and closed surfaces.Ffor the shifting-AFT, it's not necessary to introduce virtual boundaries manually and automatically while meshing a closed surface, better-shaped triangles will be generate. Comparing with direct methods, the shifting-AFT avoids carrying out costly and unstable 3D geometrical computations in real space. During rolling back of tetrahedral meshing the advancing path is changed by changing front's preferential factor, the times of rolling back is decreased significantly. Moreover, node inserting based on linear programming technique improves the convergence of the algorithm. At the end, a robust backward search method based on walk-through algorithm is proposed to deal with the searching problems in non-convex fields and to avoid the problems of infinite loop.

Book Synopsis Modeling, Mesh Generation, and Adaptive Numerical Methods for Partial Differential Equations by : Ivo Babuska
Download or read book Modeling, Mesh Generation, and Adaptive Numerical Methods for Partial Differential Equations written by Ivo Babuska. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: With considerations such as complex-dimensional geometries and nonlinearity, the computational solution of partial differential systems has become so involved that it is important to automate decisions that have been normally left to the individual. This book covers such decisions: 1) mesh generation with links to the software generating the domain geometry, 2) solution accuracy and reliability with mesh selection linked to solution generation. This book is suited for mathematicians, computer scientists and engineers and is intended to encourage interdisciplinary interaction between the diverse groups.
