摘要：

A nonlinear three-point discretization of the density-gradient equations is presented. The new method, an exponential-fitting scheme, is evaluated using numerical examples involving both quantum confinement and tunneling. The nonlinear discretization is shown to perform far better than the conventional linear version allowing for a substantial easing in the mesh refinement especially in tunneling problems.
