ABSTRACT
In this paper, we present a radial basis function based meshless method that employs Schwarz domain decomposition techniques and Newton iteration for solving nonlinear elliptic partial differential equations (PDEs). Numerical results are presented for a model nonlinear Poisson problem. We find that the domain decomposition algorithms give accurate results at a much lower cost. In addition, these algorithms are straightforward to parallelize.

Keywords:  Nonlinear PDEs; Schwarz domain decomposition; Radial basis functions; Newton iteration
