The paper describe possibilities for increase of the numerical efficiency of structural computation on the basis of the improvement of renumbering method of finite element systemjoints. It is shown that the modified Cuthill-McKee (MCM*) algorithm could serve, among others, in determination of so-called peripheral or pseudo-peripheral joint of the graph by which the finite elements system is approximated.
In several numerical examples the advantages of application of the MCM* algorithm in relation to the well known Gibbs-Poole-Stockmayer (GPS) method are illustrated. In addition, the numerical aspects of application of the finite elements method and importance of selection of the optimum algorithm for solution of equations system with view to the actual courses in the software and hardware development in small computer systems branch, are considered.
