Abstract:

The development of the ideas contained in the finite-element method and boundary element method led to the appearance of the hybrid superelement method. The system of basis functions for the superelement is constructed using the boundary element method techniques. A global approximation of the solution within the limits of the superelement often gives better results, even with a smaller number of parameters, than standard finite-element functions. Another advantage of the hybrid superelement method is that, on combining superelements, two matching conditions (for the potential and the flux) may be written in explicit form; the complete matrix of the system of equations will take the strip structure characteristic of the finite element method. In this study, the use of a superposition of solutions of Poisson's equation is proposed as the system of basis function for a finite element.
