The boundary element method, with the dual reciprocity method (DRM) is applied to an identification problem of point sources in two-dimensional potential problems. The source term consisting of multiple point sources is assumed to be a distributed source and is approximated with a linear combination of radial basis functions. By applying DRM, the domain integral originated from this assumed source term is converted into boundary integrals, so that no internal cells are needed in evaluating unknown coefficients of the approximated source distribution. From the identified source distribution, the positions of the concentrated sources are estimated by calculating the coordinates of the local maximums. Then, the intensities of the point sources are evaluated by starting from the BEM formulation with point sources.
