We propose a new stable variable mesh implicit difference method for the solution of non-linear parabolic equation uxx=Φ(x,t,u,ux,ut), 0< x< 1, t>0 subject to appropriate initial and Dirichlet boundary conditions prescribed. We require only (3 + 3)-spatial grid points and two evaluations of the function Φ. The proposed method is directly applicable to solve parabolic equation having a singularity at x = 0. The proposed method when applied to a linear diffusion equation is shown to be unconditionally stable. The numerical tests are performed to demonstrate the convergence of the proposed new method.
