Abstract
A procedure has been developed for improvement of surface triangulation quality by node repositioning as directed by a two-stage non-linear optimization technique. The surface mesh modification procedure is designed so that the quality of the triangles is improved without drastically distorting the surface. Repositioning of the nodes is done using local parametric mapping so that they remain on the triangles of the original mesh.
