Abstract
A graph theoretical approach is designed for element renumbering of finite element meshes for frontwidth reduction of sparse matrices with symmetric s tructures. In this heuristic, the problem is transformed into that of a gra ph nodal ordering. The incidence graph of a mesh is used for representing i ts connectivity. The efficiency of the method is illustrated through worst- case analysis and examples of unstructured finite element models. (C) 1999 Elsevier Science Ltd and Civil-Comp Ltd. All rights reserved.
