An Adaptive Moving Grid Method for A Singularly Perturbed Convection-Diffusion Problem

    Graphical Abstract
    • Abstract
  • A singularly of two singularly perturbed convection-diffusion problems is considered. Based on finite difference scheme, an adaptive moving grid approach to solve these problems is presented, and an iteration algorithm to generated meshes and a first-order a posteriori error estimate are given. Numerical results are presented that support our theoretical estimates.
