A General Curvilinear Grid Generation Program for Projectile Configurations

Abstract

A planar grid generation routine has been developed for use with standard and non-conventional projectile shapes. Three-dimensional grid generation has been obtained by generating a sequence of planar grids about axis normal cross-sections. The method is basically automatic and generates smoothly varying grids for arbitrary body shapes and allows for grid point clustering. The program is modular and can be used to generate planar Cartesian-like grids, C-grids, O-grids, or any portion thereof. The routine can be used for axisymmetric projectiles with or without stings, symmetric tubular projectiles and for any configuration with an axisymmetric nose. Sample grids are presented along with the program listing and sample output.
