Book Description
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and optimization, generation of hexahedral meshes, and large scale and parallel meshing, along with innovative unpublished meshing methods.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 Description
Este trabalho apresenta algoritmos de geração automática de malhas de elementos finitos bidimensionais e tridimensionais que, juntamente com outros algoritmos desenvolvidos dentro da linha de pesquisa ao qual ele está inserido, são integrados consistentemente em um pacote computacional. Os algoritmos geradores de malhas foram modificados para serem independentes dos pré-processadores, podendo assim serem incorporados em diferentes programas. Um novo algoritmo bidimensional de geração de elementos triangulares é proposto. Este algoritmo incorpora novas idéias, adaptadas de um algoritmo de geração tridimensional de malhas em volume arbitrário, e procura gerar elementos de melhor qualidade geométrica possível. Duas técnicas de geração de malhas sólidas são apresentadas: uma de mapeamento transfinito tridimensional, onde a malha sólida é construída a partir das seções transversais do modelo; e uma técnica de sweep, onde a malha sólida é construída pelo arrasto de uma seção transversal ao longo de um curva no espaço. Os algoritmos são incorporados em um modelador geométrico tridimensional, o MG (Mesh Generator), e alguns exemplos são feitos para demonstrar a capacidade de modelagem do ambiente criado. Em particular são mostrados exemplos para modelagem composta com diferentes métodos de construção de malhas e diferentes tipos de elementos finitos em um mesmo modelo. Também é feito um estudo de algumas medidas de distorção para elementos finitos planos. O cálculo dessas medidas de distorção é implementado em um modelador bidimensional gráfico interativo. A visualização das medidas de distorção é feita através de uma escala de cores.
