Fig. 1From: An efficient non-iterative smoothed particle hydrodynamics fluid simulation method with variable smoothing lengthIllustration of the variable smoothing length concept. The smoothing length of particle i is the default value h owing to the uniform distribution of particles around it, while the smoothing length of particle j has to be expanded from h to hj to maintain sufficient number of neighbors, owing to the sparse distribution of neighboring particlesBack to article page
