A NEW NUMERICAL SCHEME FOR SOLVING THE TWO DIMENSIONAL FRACTIONAL DIFFUSION EQUATION

Abstract

In this study, the locally one dimensional (LOD) method is used to solve the two dimensional time fractional diffusion equation. The fractional derivative is the Caputo fractional derivative of order a. The rate of convergence of the finite difference method is presented. It is seen that this method is in agreement with the obtained numerical solutions with acceptable central processing unit time (CPU time). Error estimates, numerical and exact results are tabulated. The graphics of errors are given.
