Advances in discrete surface grid generation - Towards a reliable industrial tool for CFD

Recent advances in Discrete Surface grid generation are described. Speci c aspects include: automatic preprocessing/improvement of the given DS grid, de nition of sharp edges, strict enforcement of continuous topology, introduction of a visibility horizon based on the geometrical features in the DS, improved 2D cross-checks, and better adaptive background grid element size de nition. The aim of this e ort is to obtain a reliability similar to that of the standard Advancing Front Method operating on analytical surfaces, but resulting in a much better quality of a global surface mesh.
