Hybrid adaptive poisson grid generation and grid smoothness
Communications in Applied Numerical Methods, 1991AbstractA hybrid technique for adaptive grid generation using a variety of Poisson grid generators is described. The technique ensures that, when adaptivity functions are weak, the adapted grid reverts to an arbitrary specified base grid rather than to the grid produced by the homogeneous elliptic generator.

Surface grid generation based on unstructured grid
Flight Simulation Technologies Conference and Exhibit, 1990cases. This finding may suggest that, at small angles of attack, lift and wake-collapse sources of internal wave generation might be usefully considered as uncoupled. The early trajectory of the wake centerline is fairly well predicted by the self-similar theory of Tulin and Shwartz, using reasonable values for the empirical parameters involved.

Parallel generation of unstructured surface grids
Engineering with Computers, 2005In this paper, a new grid generation system is presented for the parallel generation of unstructured triangular surface grids. The object-oriented design and implementation of the system, the internal components and the parallel meshing process itself are described.

An adaptive grid generator has been developed and coupled into a finite element solver for automatically performing grid refinements based on error estimators. Initial grids are constructed such that the distribution of interior points satisfies the boundary point spacing functions.

Emerging Technologies for Next-Generation GRID
2008 IEEE 17th Workshop on Enabling Technologies: Infrastructure for Collaborative Enterprises, 2005The international workshop on Emerging Technologies for Next-generation GRID (ETNGRID) is at its third edition. The number of submitted papers, as well as the topics tackled, clearly show the attention the research community has towards Grid computing, an interest which is continuously growing.

Generalized Multiresolution Analysis on Unstructured Grids
Numerische Mathematik, 1999The authors show that the efficiency of high-order essentially non-oscillatory approximations of conservation laws can be improved if ideas of multiresolution analysis (cf. Abgrall and Harten, CAM-reports 93-13, 94-10 and 94-20, University of California, Los Angeles, 1993-1994) are taken in account.These methods of data compression reduce the necessary

A method for orthogonal grid generation is presented. The generating system is based on solution of a system of partial differential equations with finite difference discretization. The influence of the number of grid points, type of boundary, and intensity of the grid quality control function and grid properties are investigated. Specification of both

Jacobian-Weighted Elliptic Grid Generation
SIAM Journal on Scientific Computing, 1996The purpose of this paper is to apply variational grid generation techniques to derive and analyze a weighted elliptic generator that controls the Jacobian of the underlying transformation in a least square sense. Examples are given on the unit square to demonstrate point attraction, local refinement, directional alignment and adaption to a shock.
