Thompson, D., & Soni, B. (2002). Semistructured Grid Generation in Three Dimensions Using a Parabolic Marching Scheme. AIAA Journal. Washington, DC: AIAA. 40(2), 391-393. DOI:10.2514/2.1659.
In this paper, a novel algorithm to generate a hexahedral-dominant, semistructured grid as a near-body component of a hybrid grid is described. The algorithm uses a parabolic marching scheme coupled with a line deletion/insertion strategy to generate grids that have structure within each layer but may lose local connectivity at the interface between layers. The basics of the approach are discussed and the algorithm is demonstrated for several example configurations. A detailed description of the algorithm is contained in the full paper.
