Investigations of boundary treatments in incompressible smoothed particle hydrodynamics for fluid-structural interactions
TL;DR: In this paper, two boundary treatment methods were developed for incompressible flow simulations and fluid-structural interaction problems using Smoothed Particle Hydrodynamics (SPH): 1) to apply repulsive force on the boundary particles while keeping the same particle spacing for inner fluid particles and wall boundary particles; 2) to use denser wall particles without any additional force.
