Pre- and Postprocessing Techniques for Determining "goodness" of Computational Meshes

Category : Aerodynamics
Languages : en
Pages : 254
Book Description
In computational fluid dynamics, finite-difference or finite-element grids are often generated using methods which can define fine meshes where required by detailed features of the flow or provide, through adaptive schemes, smooth orthogonal meshes with minimal distortion. Methods which predict the mesh goodness and the quality of the solution do not exist. This project addresses these needs through study of several pre-and post-processing techniques. In the pre-processor, guidelines for an acceptable mesh will be provided via an a-posteriori estimation of the error potentially developed with a given mesh. An adaptive technique will then pre-process the mesh before expensive calculation is performed. Post-processing will use data from a computed solution and rigorous a-posteriori error estimates to judge the overall quality of the solution and, by using extraction and extrapolation routines, enhance the solutions of important flow problems. Initial studies will focus on steady two-dimensional Euler and Navier-Stokes equations. Potential Commercial Applications: The new meshes and codes will provide a package of potentially great value to the aerospace industry.

Computational Magnetics
Author: J. Sykulski
Publisher: Springer Science & Business Media
ISBN: 9401112789
Category : Technology & Engineering
Languages : en
Pages : 386
Book Description
This book fills the gap between theory, available computational techniques and engineering practice in the design of electrical and electromechanical machines. The theory underlying all currently recommended computational and experimental methods is covered comprehensively, including field analysis and synthesis, magnetic fields coupled to stress and thermal fields. The book is very practically oriented and includes many examples of actual solutions to real devices.

ECCOMAS '96, Computational Methods in Applied Sciences '96
Author: J. A. D?sid?ri
Publisher: Wiley
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 600
Book Description
The European Community on Computational Methods in Applied Science (ECCOMAS) has been created with the aim of providing a co-ordination of international scientific conferences and other activities in the field of computational methods in applied sciences. The main objective of the joint conferences on computational fluid dynamics and numerical methods in engineering is to provide a common forum for the presentation and discussion of scientific computing applied to engineering sciences. Equal emphasis is to be given to basic methodologies, scientific developments and industrial applications. These conferences are presented in three volumes. Volume one, Computational Fluid Dynamics '96, covers the proceedings of the Third ECCOMAS Conference on Computational Fluid Dynamics; Volume two, Numerical Methods in Engineering '96, covers the proceedings of the second ECCOMAS Conference on Numerical Methods in Engineering; and Volume three, Computational Methods in Applied Sciences '96, which presents invited lectures and special technical sessions of both the Third ECCOMAS Computational Fluid Dynamics Conference and the Second ECCOMAS Conference on Numerical Methods in Engineering.
