摘要

Three-dimensional structured grid generation methodology based on elliptic partial differential equation (PDE) method is reviewed. It will be shown that the quality of a grid depends on how to treat the second normal derivative terms involved in control functions. A 7-point finite analytic scheme based on one-dimensional analytic solution will be introduced to discretize the governing equations of the elliptic grid generation.
