Numerical Simulation of Diffusion Equation by Means of He's Variational Iteration Method and Adomian's Decomposition Method


In this study, we obtain approximate solutions for diffusion equation on a finiteinterval by the Adomian decomposition method (ADM) and variational iteration method(VIM) for three cases and then the numerical results are compared. These results showthat the ADM leads to more accurate results, and they indicate that only a few terms aresufficient to obtain accurate solutions.
