Local Poisson SPH For Viscous Incompressible Fluids
TL;DR: This paper presents a local Poisson SPH (LPSPH) method to solve incompressibility for particle based fluid simulation that can effectively eliminate the large density deviations mainly caused by the solid boundary treatment and free surface topological change, and show advantage of a higher convergence rate over the predictive‐corrective incompressible SPH.

Space potential particles to enhance the stability of projection-based particle methods
TL;DR: In this paper, a simple and effective scheme as a free-surface boundary condition of projection-based particle methods, namely the MPS (moving particle semi-implicit) and Incompressible SPH (ISPH) methods, is presented to handle the free surface with consistency in volume conservation.

Smoothed Particle Hydrodynamics: Approximate zero-consistent 2-D boundary conditions and still shallow-water tests
TL;DR: In this paper, an approximate modified virtual boundary particle method (MVBP) for solid boundary conditions in a two-dimensional smoothed particle hydrodynamics (SPH) model is presented; this is a development of the original VBP method recently proposed by Ferrari et al. The method is also demonstrated for the dynamic case of a circular dam break interacting with an outer circular wall where conventional mirror particles fail to prevent particles passing through the solid wall.

TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.
