Analytical results (red curves) and numerical results of the AB model (symbols) for h(x,t) and x N(t). a ρ c/ρ a=1.01. b ρ c/ρ a=1000. In the numerical results, blue symbols represent the numerical results given ε based on the analytical solution during the slumping stage (a ε=6.58×10−2; b ε=4.58×10−7). Green symbols represent the numerical results given ε=1.0×10−10
