In this article, using three function evaluations, we discuss a nine-point compact scheme of O( triangle y(2) + triangle x(4)) based on numerovtype discretization for the solution of 2D quasi-linear elliptic equations with given Dirichlet boundary conditions, where triangle y > 0 and triangle x > 0 are grid sizes in y-and x-directions, respectively. Iterative methods for diffusion-convection equation are discussed in detail. We use block iterative methods to solve the system of algebraic linear and nonlinear difference equations. Comparative results of some physical problems are given to illustrate the usefulness of the proposed method.
