The strategy of reusing the integral equation of the Boundary Element Method (BEM) to improve the
accuracy of the values of variables previously calculated on the boundary have showed consistency, addressing
scalar problems governed by the Laplace, Poisson, and Navier equations. In this work, the boundary nodal
values obtained with the application of the Finite Element Method (FEM) in Poisson problems are substituted in
the BEM integral equation for the calculation of the internal values of potential and its derivative. For the
example showed, the results obtained were compared with the values found by the FEM and BEM, both in their
classic form, and the performance was evaluated through the analytical results.
