Delaunay refinement
In mesh generation, Delaunay refinements are algorithms for mesh generation based on the principle of adding Steiner points to the geometry of an input to be meshed, in a way that causes the Delaunay triangulation or constrained Delaunay triangulation of the augmented input to meet the quality requirements of the meshing application. == Motivation == When doing computer simulations such as computational fluid dynamics, one starts with a model such as a 2D outline of a wing section.
