Comparison between two different steady state functions of u by applying our model using different initial guess functions of u. For the left graph of u, we choose 0 function as the initial guess of u, while the right one corresponds to the initial guess u = f. In the left graph, the narrow dip was removed, but it was kept on the right graph. This phenomenon is intrinsic to our model because of the independence of the first mean curvature on the height of jumps. In these two experiments, the parameters are both dt = 0.000005, ∏ = 0.0015.
