This paper presents a hybrid approach coupling natural element method (NEM) and boundary element method (BEM) for the treatment of unbounded problems. The goal is to combine the accuracy of the NEM and the ability of the BEM in modeling linear and deformable domains without a mesh. The performance of the proposed scheme is compared to a FEM-BEM coupling in terms of accuracy. Results show that for a given number of degrees of freedom the proposed approach (NEM-BEM) is able to provide more accurate solutions.
