An algorithm for surface domain decomposition and grid generation for overset grids is described. A complex surface domain is covered by two types of grids: seam grids and block grids. Seam grids are grids used to wrap around surface crease lines and regions of high surface curvature. Block grids are grids that cover the remaining surface regions not occupied by the seam grids. The seam and block grids form a set of overlapping surface grids that cover the entire surface geometry. Given a set of seam grids, an automated method for generating the block grids is presented in this paper. Examples of seam and block grids are given for several configurations including the V-22 tiltrotor fuselage and the X-CRV Crew Return Vehicle.
