Graphene sheet at 5000 K simulated with the empirical potential LCBOPII  analyzed with polypy
Example potential energy surface explored using NEB. The NEB method converges to a steepest descent path with equidistant images on both sides of the climbing image. The climbing image is chosen asymmetric for illustration purpose. Images are shown in red, the climbing image in blue, and contour lines are plotted at -0.5, 0, 0.5 and 1.0.
