Fig. 5From: An efficient non-iterative smoothed particle hydrodynamics fluid simulation method with variable smoothing lengthSimulation of water flow impacting a sculpture in ruins using the VSLSPH (top) and DFSPH [9, 10] (bottom) methods, with 20000 particles, where the number of neighbors per particle is shown by different colors, from purple to red. In the DFSPH case, many of the particles at the splash site are purple and the ones at the fluid surface are blue, while in the VSLSPH case, particles at the splash site are blue and the ones at the fluid surface are green, showing a better distribution of the number of neighborsBack to article page
