- Triangular grid generators for the eigenvalue calculation with edge elements G.M. Ortigoza Capetillo Física, Astronomía y Matemáticas RCM ordering edge elements generalized eigenproblem Triangular grid generators In this work we investigate some computational aspects of the eigenvalue calculation with edge elements, those include: the importance of the grid generator and node-edge numbering. As the examples show, the sparse structure of the mass and stiffness matrices is highly influenced by the edge numbering of the different grid generators tested. Significant bandwidth reduction can be obtained by the proper combination of the edge numbering scheme with the grid generator method. Moreover, an ordering algorithm such as the Reverse Cuthill-McKee can improve the bandwidth reduction which is necessary to reduce storage requirements. 2009 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57028304003 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
