Richardson extrapolation technique on a modified graded mesh for singularly perturbed parabolic convection-diffusion problems

In this paper, we focus on investigating a post-processing technique de-signed for one-dimensional singularly perturbed parabolic convection-diffusion problems that demonstrate a regular boundary layer. We use a back-ward Euler numerical approach for time derivatives with uniform mesh in the tempora...
