A novel algorithm to generate quad- and hex-dominant, semistructured meshes is
presented. The algorithm utilizes a three-step, advancing layer scheme to
generate the mesh in structured layers starting from an initial data surface.
First, a locally orthogonal reference mesh is algebraically generated. The
reference mesh is then smoothed using a Poisson-type mesh generation equation.
Finally, a line deletion/insertion algorithm based on cell geometry is applied
as the initial data surface for the next layer is defined. Typically, for meshes
appropriate for viscous flow calculations, more than 95% of the cells are
quadrilaterals or hexahedra. The resulting mesh offers a potentially attractive
alternative for near-body regions of hybrid meshes. Several preliminary examples
are included to demonstrate the efficacy of the approach.
