Structured grid generation

A structured grid creates an arrangement of quad (2d) or brick (3d) grid cells that are arranged in a simple matrix-like structure. Unlike a Cartesian grid in which the cells are always regularly shaped, a structured grid is warped to follow the boundaries of the system. The node arrangement in the grid follows the same … See more This is the simplest type of grid generation technique. In this method, a rectangular grid is used to represent the boundary and interior of a system for use in a CFD simulation, with grid … See more This grid generation method for CFD simulations applies a multi-structured approach to complex shapes that could conform to different coordinate systems. For example, consider … See more An unstructured grid is a tessellation across the surface and interior volume of the system, seen as triangles (in 2D problems) or tetrahedra (in 3D problems).

WebThe treatment of structured grid generation starts with basic geometry and tensor analysis before moving on to identify the variety of approaches that can be employed in the generation of structured grids. The book then introduces unstructured grid generation by explaining the basics of Delaunay triangulation and advancing front techniques. Many meshing techniques are built on the principles of the Delaunay triangulation, together with rules for adding vertices, such as Ruppert's algorithm. A distinguishing feature is that an initial coarse mesh of the entire space is formed, then vertices and triangles are added. In contrast, advancing front algorithms start from the domain boundary, and add elements incrementally fil…
