Abstract

A FEM-BEM coupling procedure through the Steklov-Poincare operator R. Perera*, A. Ruiz*, E. Alarcon* *Escuela Tecnica Superior de Ingenieros Industrials de Madrid, Spain Escuela Tecnica Superior de Ingenieros de Minas de Madrid, Spain ABSTRACT Many advantages can be got in combining finite and boundary elements. It is the case, for example, of unbounded field problems where boundary elements can provide the appropriate conditions to represent the infinite domain while finite elements are suitable for more complex properties in the near domain. However, in spite of it, other disadvantages can appear. It would be, for instance, the loss of symmetry in the finite elements stiffness matrix, when the combination is made. On the other hand, in our days, with the strong irruption of the parallel proccessing the techniques of decomposition of domains are getting the interest of numerous scientists. With their application it is possible to separate the resolution of
