Proven Angular Bounds and Stretched Triangulations With the Frontal Delaunay Method
Jens-Dominik Miiller · 1993
An unstructured grid generation method based os the Delaunay triangulation is presented that is capable of generating stretched layers along surface lines while retaining strong control over maximum angles. The method requires only minimum user input in form of a set of boundary nodes, the character of each boundary, the thickness of the stretched layer and the maximum aspect ratio desired. Upper and lower angular bounds and an upper bound in surface variation between neighboring cells are proven.
