Abstract

In this paper, we continue the study on the application of multinode Shepard method to numerically solve elliptic Partial Differential Equations (PDEs) equipped with various conditions at the boundary of domains of different shapes. In particular, for the first time, the multinode Shepard method is proposed to solve elliptic PDEs with Dirichlet and/or Neumann boundary conditions. The method has been opportunely handled to efficiently work dealing with scattered distribution of points and, to this aim, several exper- iments in different 2d domains have been performed. Comparisons with the analytic solution and the results generated by the Kansa’s RBF solvers have been reported referring to Halton points. The results are very promising and should be of interest for applications in the real world.
