A Discussion on a Mesh Generation Technique Applicable to Complex Geometries,
Abstract
This paper describes a general three dimensional block structured grid generation technique which has been coupled with an Euler algorithm to simulate the flow around complicated aerodynamic configurations. The flow field is subdivided into a set of non-overlapping blocks and grids are generated simultaneously in all of the blocks using an elliptic grid generation method. Appropriate boundary conditions applied on the face of the blocks ensure that grid lines pass smoothly between blocks leaving the grid globally smooth. Details of the surface and field grid generation are given and techniques to control the position of grid points are highlighted. Grid topologies for complicated civil and military configurations are discussed. Examples are given of grids for complicated configurations and some results of flow calculations on block structured grids are shown.
