Accuracy and stability in incompressible SPH (ISPH) based on the projection method and a new approach
TL;DR: A new divergence-free ISPH approach is proposed here which maintains accuracy and stability while remaining mesh free without increasing computational cost by slightly shifting particles away from streamlines, although the necessary interpolation of hydrodynamic characteristics means the formulation ceases to be strictly conservative.

Comparisons of weakly compressible and truly incompressible algorithms for the SPH mesh free particle method
TL;DR: Comparisons of a semi-implicit and truly incompressible SPH (ISPH) algorithm with the classical WCSPH method are presented, showing how some of the problems encountered inWCSPH have been resolved by using ISPH to simulate incompressable flows.

Incompressible smoothed particle hydrodynamics for free-surface flows: A generalised diffusion-based algorithm for stability and validations for impulsive flows and propagating waves
TL;DR: The algorithm is based upon Fick's law of diffusion and shifts particles in a manner that prevents highly anisotropic distributions and the onset of numerical instability, and is validated against analytical solutions for an internal flow at higher Reynolds numbers than previously.
