Abstract :
An improved placement of the integration surface for the integral equation in the hybrid FEM-RBCI method is achieved by selecting such surface as lying in the middle of tetrahedral finite elements. A better accuracy is obtained with respect to the case in which the integration surface lies along the finite element faces.
