Abstract

In recent years interest has been developed in generating numerical grids required for the solution of aerodynamic problems and other problems governed by partial differential equations ,on arbitrary regions. The importance of this
subject stems from the fact that poor grids may cause results to be erroneous and that they may fail to reveal the critical aspects of the true solution. The acute shortage of proper computational resources in our educational institutions contributes to the lag in knowledge of this area in Egypt. This work outlines the state of the art in the two dimensional grid generation and presents the results of an effort made to provide a new low cost grid generator using a micro computer. The algorithm presented belongs to the type of differential system and produces orthogonal grids. Examples from the program outputs are included. Also, a methodology for evaluating the output grid is briefly presented.
