Abstract
A generalized unstructured mesh generation procedure using Delaunay tr iangulation has been developed for adaptive finite element application s. The main features of the method include: (i) a fast and efficient i nitial triangulation; (ii) interior node insertion with good control o ver the grid size and aspect ratio distribution; (iii) a flux-based er ror across element boundaries. The scheme has been applied successfull y to heat transfer problems involving steep temperature gradients. (C) 1997 John Wiley & Sons, Ltd.
