The consistent development of the conventional boundary elements method (CBEM) by adding the concepts of the hybrid boundary element simplified method (HBEM) , from the Hellinger-Reissner variational potential leads to a computationally less intensive procedure, although not necessarily less accurate for large scale, two-dimensional or three-dimensional problems of potential and elasticity. It was shown that both single-layer and double-layer potential matrices, G and H, respectively, are obtained in an expeditious way that vanish almost any numerical integration, except for a few regular integrals, even G and H evaluation requires the handling of singular and improper integrals. The proposed formulation comes from the HBEM variational base and its evaluation at internal points is straightforward without the application of any boundary integral, since the fundamental solution is the analytical one. This work belongs to a project that aims a computer code for large-scale problems (millions of degrees of freedom). At this stage, some numerical examples were analyzed to evaluate the applicability of the method expeditious its computational effort and convergence of the results for the variables involved in the method. It was developed by the algorithms implementation for potential and elasticity problems. In the case of two-dimensional were employed linear, quadratic and cubic elements and to the three-dimensional case were employed triangular, quadrilateral, linear and quadratic elements in both cases. The computational codes were always implemented focused on solving largescale problems. It is expected that in a final stage of the project with the incorporation procedure of the method fast multipole, it can be more efficiently.
