Grid Generation Methods

Vladimir-D Liseikin

This new edition provides a description of current developments relating to grid methods, grid codes, and their applications to actual problems. Grid generation methods are indispensable for the numerical solution of differential equations. Adaptive grid-mapping techniques, in particular, are the main focus and represent a promising tool to deal with systems with singularities. This 3rd edition includes three new chapters on numerical implementations (10), control of grid properties (11), and applications to mechanical, fluid, and plasma related problems (13). Also the other chapters have been updated including new topics, such as curvatures of discrete surfaces (3). Concise descriptions of hybrid mesh generation, drag and sweeping methods, parallel algorithms for mesh generation have been included too. This new edition addresses a broad range of readers : students, researchers, and practitioners in applied mathematics, mechanics, engineering, physics and other areas of applications.

One of the simplest methods for indirect quadrilateral mesh generation includes dividing all triangles into three quadrilaterals, as shown in Figure 6. This method  ...

Chapter 5: Hyperbolic Methods for Surface and Field Grid ... equation methods for structured surface grid generation and field grid generation. In hyperbolic grid generation, a mesh is generated by propagating in the normal direction from a known level of points to a new level of points, starting from a given initial state. For two-dimensional
