Numbering of Finite Element Mesh Nodes

OUYANG Xing CHEN Zhong kui SHI Fa zhong (Beijing University of Aeronautics and Astronautics, School of Mechanical Engineering and Automation)  
In finite element analysis, the storage needed by a total stiffness matrix for solving a large scale system of linear equations is related to the sequenace determined by numbering of mesh nodes. Based on the solutions for both constant and varible bandwidth storages, their relationship is derived. On the above basis, the frontal method and rectangle method are proposed, the relationships between memory spending for both methods and amount of nodes are given. Theoretical analyzing and practical examples have proved that the two methods can efficiently decrease the memory spending of computer.
