The variational iteration method for solving linear and nonlinear systems of PDEs

In this work, the variational iteration method (VIM) is used for analytic treatment of the linear and nonlinear systems of partial differential equations. The method reduces the calculation size and overcomes the difficulty of handling nonlinear terms. Numerical examples are examined to highlight the significant features of the VIM method. The method shows improvements over existing numerical techniques. (c) 2007 Elsevier Ltd. All rights reserved.
