Triangle
Utility

Introduction For mesh refinement, we will use the constrained Delaunay triangulation utility Triangle, written by Jonathan Shewchuck. Triangle is a C program which produces a finite element mesh from a set of points and domain boundaries. A MATLAB interface to the utility is provided which returns a triangle mesh for a set of points and boundary edges.

Interface Details The triangulate function provides an interface to the Triangle utility in MATLAB. triangulate accepts a set of points and a list of boundary edges as input, and returns a triangulation of the domain by Triangle as a new set of points and a list of mesh triangles. See the tridemo program for an example of this procedure.To implement a general mesh refinement procedure, one might repeat the following steps until a desirable triangulation is obtained:
