Has anyone else encountered an issue with degenerate faces in a Constrained Delaunay Triangulation?
I'm trying to generate a Delaunay triangulation of a square domain that has non-axis aligned sides. When I run two refinement steps, the mesh contains 4 triangles, with 1 degenerate triangle with area 0. I expect to have 3 triangles. It appears that the degenerate triangle is generated with the star_hole when the new point in the refinement is inserted. I haven't seen a place where there is a check for area 0 (or very small area) triangles and subsequent removal. Any suggestions would be wonderful.
