The standard "nite element method (FEM) is unreliable to compute approximate solutions of the Helmholtz equation for high wave numbers due to the dispersion, unless highly re"ned meshes are used, leading to unacceptable resolution times. The paper presents an application of the element-free Galerkin
In this article we analyze the well-posedness (unique solvability, stability, and CΓ©a's estimate) of a family of Galerkin schemes for the coupling of fluid flow with porous media flow. Flows are governed by the Stokes and Darcy equations, respectively, and the corresponding transmission conditions a
