Abstract
Methods are presented for selecting a good starting node and a suitable transversal for their application in nodal numbering of a structure .A new connectivity coordinate system is defined for systematic description of the nodal ordering algorithm. Applications are extended to element ordering for optimizing the bandwidth of flexibility matrices, and bandwidth and frontwidth of finite element models.
