Book Fundamentals of Grid Generation

Download or read book Fundamentals of Grid Generation written by Patrick Knupp and published by CRC Press. This book was released on 2020-12-17 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Grid Generation is an outstanding text/reference designed to introduce students in applied mathematics, mechanical engineering, and aerospace engineering to structured grid generation. It provides excellent reference material for practitioners in industry, and it presents new concepts to researchers. Readers will learn what boundary-conforming grids are, how to generate them, and how to devise their own methods. The text is written in a clear, intuitive style that doesn't get bogged down in unnecessary abstractions. Topics covered include planar, surface, and 3-D grid generation; numerical techniques; solution adaptivity; the finite volume approach to discretization of hosted equations; concepts from elementary differential geometry; and the transformation of differential operators to general coordinate systems. The book also reviews the literature on algebraic, conformal, orthogonal, hyperbolic, parabolic, elliptic, biharmonic, and variational approaches to grid generation. This unique volume closes with the author's original methods of variational grid generation.

Book The Three Dimensional Multi Block Advanced Grid Generation System  3dmaggs

Download or read book The Three Dimensional Multi Block Advanced Grid Generation System 3dmaggs written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-17 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the size and complexity of three dimensional volume grids increases, there is a growing need for fast and efficient 3D volumetric elliptic grid solvers. Present day solvers are limited by computational speed and do not have all the capabilities such as interior volume grid clustering control, viscous grid clustering at the wall of a configuration, truncation error limiters, and convergence optimization residing in one code. A new volume grid generator, 3DMAGGS (Three-Dimensional Multi-Block Advanced Grid Generation System), which is based on the 3DGRAPE code, has evolved to meet these needs. This is a manual for the usage of 3DMAGGS and contains five sections, including the motivations and usage, a GRIDGEN interface, a grid quality analysis tool, a sample case for verifying correct operation of the code, and a comparison to both 3DGRAPE and GRIDGEN3D. Since it was derived from 3DGRAPE, this technical memorandum should be used in conjunction with the 3DGRAPE manual (NASA TM-102224). Alter, Stephen J. and Weilmuenster, Kenneth J.

Book Transformation of Two and Three Dimensional Regions by Elliptic Systems

Download or read book Transformation of Two and Three Dimensional Regions by Elliptic Systems written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2019-01-04 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: During this contract period, our work has focused on improvements to elliptic grid generation methods. There are two principle objectives in this project. One objective is to make the elliptic methods more reliable and efficient, and the other is to construct a modular code that can be incorporated into the National Grid Project (NGP), or any other grid generation code. Progress has been made in meeting both of these objectives. The two objectives are actually complementary. As the code development for the NGP progresses, we see many areas where improvements in algorithms can be made. Mastin, C. Wayne NASA-CR-192955, NAS 1.26:192955 NSG-1577...

Book Three Dimensional Grid Generation for Complex Configurations

Download or read book Three Dimensional Grid Generation for Complex Configurations written by J. F. Thompson and published by . This book was released on 1988 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This AGARDograph surveys some of the capabilities of the CFD community for griding complex three-dimensional configurations. The intent is to provide some insight as to the present state of grid generation for aircraft configurations in order to help assess whether this task presents a long term stumbling block to routine use of CFD in aerodynamic applications. This AGARDograph begins with a brief review of some of the techniques that are available for generating body-conforming curvilinear grids. In order to assess capabilities in grid generation, colleagues at selected institutions were solicited to describe their experiences and difficulties in grid generation of complex configurations. The intent here was not to describe the very latest in grid generation procedures, but to solicit honest comments about what are the difficulties in generating practical grids and what steps are taken to meet these difficulties. These experiences, which comprise the heart of this AGARDograph, are presented as case histories. Keywords: Computational fluid dynamics; Nato furnished; Aerodynamic configuration; Grids(coordinates); Computation; Computer graphics; Wing body configurations; Generating functions; Evaluation.

Book Three Dimensional Solution Adaptive Grid Generation on Composite Configurations

Download or read book Three Dimensional Solution Adaptive Grid Generation on Composite Configurations written by Yen Tu and published by . This book was released on 1989 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: A solution-adaptive grid generation procedure is developed and applied to three-dimensional inviscid transonic fluid flow around complex geometries using a composite block grid structure. The adaption is based upon control functions in an elliptic grid generation system. The control function is constructed in a manner such that a proper grid network can be generated as a fluid flow solution is evolving. The grid network is boundary-conforming for accurate representation of boundary conditions. The procedure implemented allows orthogonality at boundaries for more accurate computations, while smoothness is implicit in the elliptic equations. The approach allows multiple-block grid systems to be constructed to treat complex configurations as well. The solution-adaptive computational procedure has been accomplished by coupling the elliptic grid generation technique with an implicit, finite volume, upwind Euler flow solver. In simulating transonic fluid flow around a finned body of revolution and a multiple store configuration, the grid systems adapt to pressure gradients in the flow field. Results obtained show that the technique is capable of generating grid networks proper for the simulations of aerodynamics around complex configurations. Keywords: Computational fluid dynamics, Euler equations. (kr).
