Efficient implementation of the exact numerical far field boundary condition for Poisson equation on an infinite domain
An efficient numerical method for far field boundary conditions of the Poisson equation in unbounded domains is presented. In particular, one solves the Poisson equation with a false Dirichlet boundary condition, from which the correct solution can be obtained. The method is independent of the discretization, so that finite difference or finite element schemes could be employed.
