Fig. 3From: An efficient non-iterative smoothed particle hydrodynamics fluid simulation method with variable smoothing lengthSimulations of a 2D dam-break scene (5476 particles) using different methods, where the number of neighbors per particle is shown by different colors, ranging from purple to red.
