Structured flowbased gridding and upscaling for modeling ...

In this paper, several structured grid generation procedures, specifically a streamlinebased method, a Jacobianbased elliptic grid generation approach, and an optimization technique, are investigated for this purpose. The ability of the more advanced methods to resolve both flow information and geological features is illustrated.

Rectangular Grids | Gridding Systems CFD | CFD101

Useful Extensions to Rectangular Gridding. Most techniques for doing computational fluid dynamics rely on the subdivision of space into a grid of discrete volume elements in which average values of flow variables can be defined. The simplest kind of grid is one composed of rectangular elements defined by a set of planes perpendicular to each of the coordinate axes (x,y,z).

On the Grid » Mike on MATLAB Graphics MATLAB Simulink

The triangle mesh is nice and compact, and it often has fewer gridding artifacts. In particular, it naturally handles that case where the spacing between the points varies a lot by placing more triangles where the data is sampled more finely. On the other hand, MATLAB has more visualization techniques which work on a structured grid.
