Template-based quadrilateral mesh generation from imaging data
(SPRINGER, 2011)
This paper describes a novel template-based meshing approach for generating good quality quadrilateral meshes from 2D digital images. This approach builds upon an existing image-based mesh generation technique called Imeshp, ...
Template-based quadrilateral meshing
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Generating quadrilateral meshes is a highly non-trivial task, as design decisions are frequently driven by specific application demands. Automatic techniques can optimize objective quality metrics, such as mesh regularity, ...
Refinamento de superfícies de quadriláteros baseado em templates
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2013-07-11)
The computational representation of objects by means of polygonal meshes is widely used in various areas such as modeling, simulation, engineering, rendering process and various other CAD (Computer-Aided Design) and CAE ...
All-hexahedral element meshing: Automatic elimination of self-intersecting dual lines
(John Wiley & Sons Ltd, 2002-12)
There has been some degree of success in all-hexahedral meshing. Standard methods start with the object geometry defined by means of an all-quadrilateral mesh, followed by the use of the combinatorial dual to the ...
All hexahedral element meshing: Generation of the dual mesh by recurrent subdivision
(Elsevier Science Sa, 2000-02)
The domain geometry is defined by means of a closed all-quadrilateral mesh. The outer mesh imposes very strong restrictions on the possible connectivities between the inner hexahedral elements. Following the guidelines of ...
Lepp Terminal Centroid Method for Quality Triangulation: A Study on a New Algorithm
(2010)
We introduce a new Lepp-Delaunay algorithm for quality
triangulation. For every bad triangle t with smallest angle less than a
threshold angle θ, a Lepp-search is used to find an associated convex terminal
quadrilateral ...
Two Families Of H(div) Mixed Finite Elements On Quadrilaterals Of Minimal Dimension
(SIAM PublicationsPhiladelphia, 2016)
Analyzing static three-dimensional elastic domains with a new infinite boundary element formulation
(ELSEVIER SCI LTD, 2010)
A new two-dimensionally mapped infinite boundary element (IBE) is presented. The formulation is based on a triangular boundary element (BE) with linear shape functions instead of the quadrilateral IBEs usually found in the ...
