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
