Grid Generation and Algebraic Solvers

2022
This work focuses on some of the most relevant numerical issues in the solution of the drift-diffusion model for semiconductor devices. The drift-diffusion model consists of an elliptic and two parabolic partial differential equations which are nonlinearly coupled.

Elliptic Grid Generation

AIAA Journal, 1999
Conclusions Some modiŽ cations for the restriction and prolongation process of multigrid methods have been presented that are necessary for the simulation of complex supersonic  owŽ elds. Damping of the restricted residual error and blending between a second-order central and a Ž rst-order upwind prolongation enable convergence in supersonic  ows and

The grid as generator

Architectural Research Quarterly, 2000
One of the sad oddities of academic life is that great and original contributions get cursorily noticed at the time of their appearance, and are then ignored. Leslie Martin's ‘The Grid as Generator’ is one such case. Published in the book he co-authored with Lionel March in 1972, this opening essay – and indeed the entire book – represented an ...

A general grid-clustering approach

Pattern Recognition Letters, 2008
Hierarchical clustering is an important part of cluster analysis. Based on various theories, numerous hierarchical clustering algorithms have been developed, and new clustering algorithms continue to appear in the literature. It is known that both divisive and agglomerative clustering algorithms in hierarchical clustering play a pivotal role in data ...

Structured and Unstructured Grid Generation

2020
Current techniques in composite-block-structured grid generation and unstructured grid generation for general 3D geometries are summarized, including both algebraic and elliptic generation procedures for the former and Delaunay tessellations for the latter. Citations of relevant theory are given.

A Fast Algorithm for Grid Generation

Journal of Computational Physics, 1993
The authors develop a fast algorithm for grid generation for solving complex fluid dynamics problems. The grid generation equations are initialised with Laplacian counterpart and good results are shown using a VAX-3400 computer. An extension of the proposed algorithm is also discussed.
