“…In this paper, a meshless-based integration method as in [26,27,38], named the Radial Basis Integration Method (RBIM) has been developed for the computation of inertial domain integrals that are found in the BEM formulation of the 2D scalar wave equation. Using this quadrature, it is possible to compute them directly, therefore, it is a potential alternative in relation to the existent methods.…”
