| الوصف: | We use inverted finite elements method for approximating solutions of second order elliptic equations with non-constant coefficients varying to infinity in the exterior of a 2D bounded obstacle, when a Neumann boundary condition is considered. After proposing an appropriate functional framework for the deployment of the method, we analyse its convergence and detail its implementation. Numerical tests performed after implementation confirm convergence and high efficiency of the method. |
