On a Theory of Mesh-Refinement Processes

SIAM Journal on Numerical Analysis, 1980
A general theory of mesh-refinement processes is developed. The fundamental structure is a locally finite, rooted tree with nodes representing the subdivision cells. The possible meshes then constitute a distributive lattice. Under mild conditions on the given cell-size and error-indicator functions a local Pareto-type optimality property is introduced

A new scheme for mesh generation and mesh refinement using graph theory

Computers & Structures, 1993
This paper presents a new scheme for finite element mesh generation and mesh refinement using concepts from graph theory. This new technique, which is suitable for an interactive graphical environment, can also be used efficiently for fully automatic remeshing in association with self- adaptive schemes.

Parameterization of mesh-models

Proceedings of the 2006 ACM symposium on Solid and physical modeling, 2006
Mesh parameterization has been a very active research topic for the last several years, since it appeared as a fundamental tool for a wide class of problems in Digital Geometry. Its applications include texture mapping, geometry processing, remeshing, pasting, morphing, compression and reconstruction to name but a few. Computing a parameterization of a

An application of graph theory in plotting finite element mesh

Computer-Aided Design, 1984
Plotting the finite element mesh is an essential and time-consuming job for a civil engineer. An application of graph theoretic concepts like Euler Graph and unicursal graph in plotting implies a reduction in plotting time and improvement in the quality of plot output. A graph algorithm is described in this paper.

Thin capacitive meshes on a dielectric boundary: theory and experiment

Applied Optics, 1989
A rigorous formulation is used to calculate the transmission properties of a thin, perfectly conducting biperiodic capacitive mesh on a dielectric boundary. The formulation is analogous to the well-known modal method used for inductive meshes, with the modal electric fields replaced by modal currents.

Implementation of the Theory of Critical Distances using mesh control

Theoretical and Applied Fracture Mechanics, 2017
Abstract The Theory of Critical Distances (TCD) is a method for predicting fatigue and fracture at stress concentration features. It is extensively used in the design of engineering components, being a relatively simple approach based on post processing of finite element analysis (FEA).

Mesh generation and mesh adaptivity : theory and techniques

2018
In this chapter we are concerned with mesh generation methods and mesh adaptivity issues. Nowadays, many techniques are available to complete meshes of arbitrary domains for computational purposes. Planar, surface and volume meshing have been automated to a large extent. Over the last few years, meshing activities have focused on adaptive schemes where

A mesh generation method based on set theory

Computers & Structures, 1973
Abstract A method is proposed to study automatic generation of input data to finite element programs by the computer with minimal human involvement. Based on a set of objective criteria, a consistent procedure is developed to scan through the geometric idealization of a boundary to form regions for mesh generation.

Contemporary Compatibilism: Mesh Theories and Reasons-Responsive Theories

2012
AbstractThis article considers two of the most widely discussed types of new compatibilist theories under the headings of “mesh theories” and “reasons-responsive theories.” The first part of the article examines hierarchical theories, focusing initially on Frankfurt's theory, which is the most widely discussed of such theories. It considers three kinds
