An implicit boundary approach for viscous compressible high Reynolds flows using a hybrid remeshed particle hydrodynamics method
TL;DR: In this article, an implicit boundary particle method with background mesh adaptation is proposed to simulate viscous flow with high Reynolds numbers, where the boundary conditions are enforced to a specific precision with no need to modify the numerical method or change the grid, achieving an implicit approach for flow around complex boundaries/geometries simulation.

Analysis of the incompressibility constraint in the Smoothed Particle Hydrodynamics method
TL;DR: In this article, a thorough comparison of three different incompressibility treatments in SPH: weakly compressible approach, where a suitably chosen equation of state is used; and two truly incompressible methods, where the velocity field projection onto a divergence-free space is performed.

Pengcheng Yu,Pengcheng Yu,Guangqi Chen,Xinyan Peng,Xinyan Peng,Yingbin Zhang,Hong Zhang,Wei Wang +7 more
TL;DR: In this article, a coupled method is introduced to simulate FSI problems in two-dimensional (2D) case, where the smoothed particle hydrodynamics (SPH) is employed to represent the fluid domain governed by Navier-Stokes equations and the discontinuous deformation analysis (DDA) based on the minimum total potential energy principle is used to model the real solid structure (with rigidity or elasticity).
