Abstract
The effectiveness of four simple point insertion methods for generating triangular meshes by adaptive refinement is investigated computationally. Three of the methods are forms of Delaunay insertion and the fourth is Rivara's recursive longest edge bisection. The methods are used with anisotropic mesh generation techniques as heuristics for optimal error control meshing. The performance of the methods relative to optimal meshing is discussed.
