This paper investigates the possibility of using a boundary integral equation to facilitate the generation of multi‐block grid systems about semi‐complex geometries. The integral equation utilized is that for a source density distribution over the surface of the body about which the conforming grid system is sought. Advantages of and restrictions to the current method are discussed in relation with other gridding techniques. Sample grid systems are provided for several dissimilar geometric shapes which illustrate the quality and robustness of the present scheme. Copyright © 2000 John Wiley & Sons, Ltd.
