UNSTRUCTURED MESH GENERATION: THEORY, PRACTICE, AND PERSPECTIVES

International Journal of Computational Geometry & Applications, 2000
Mesh generation is a great example of inter-disciplinary research. Its development is built upon advances in computational and combinatorial geometry, data structures, numerical analysis, and scientific applications. Its success is justified not only by mathematical proofs about the quality and the numerical relevancy of geometry-based meshing ...

Mesh Theory for Toroidal Drive

Journal of Mechanical Design, 2003
In this study, a simpler mesh equation for the toroidal drive is developed. Based on the equation, equations of the contact line, the limit curves, the induced normal curvature between the mating surfaces and the angle of the relative velocity vector to the contact line are introduced.

Wireless mesh networking: theories, protocols, and systems

IEEE Wireless Communications, 2006
ireless mesh networking has become an indispensable technique for next-generation wireless networks. It is a critical solution to deploying large-scale wireless networks without relying on preexisting infrastructure. It also enables quick and easy extension of local area networks into a wide area.

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

Meshing theory of mismatched ZC1 worm drive

Mechanism and Machine Theory, 2020
Abstract The main purpose of this article is to investigate the meshing theory for the mismatched ZC1 worm drive. The contact endpoints, the datum point, and the internal instantaneous contact points are all determined by solving their corresponding nonlinear equation sets iteratively.

Meshing Theory of ZC1 Worm Drive

Volume 10: 2019 International Power Transmission and Gearing Conference, 2019
Abstract The toroidal enveloping cylindrical worm drive, also called the ZC1 worm drive, is grinded by the toroidal grinding wheel. In this paper, the meshing theory for this worm drive is systematically established. According to this meshing theory, the meshing function, the meshing limit function, the equations of the worm helicoid and

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

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.
