Abstract

We present a new non-overlapping domain decomposition method (NDDM) based on the square-root transmission conditions and the utilization of an appropriate technique dealing with the so-called cross-points problem in the context of a nodal finite element method (FEM). The square-root operator is localized using the Padé Approximants technique. In addition,we use a Krylov solver to accelerate the iterative procedure. Several numerical results are displayed to validate this new algorithm.
