ABSTRACT
Our method shortens the time of fluid simulation by coupling the two conditions of density-invariant and divergence-free, and achieves the same simulation effect compared with other methods. Further, we regard the displacement of particles as the only basic variable of the continuity equation, which improves the stability of the fluid to a certain extent.

Divergence-Free SPH Fluid Simulation Using Density Constraint Condition
In this paper, a novel, incompressible fluid simulation framework based on the divergence-free Smoothed Particle Hydrodynamics model is presented. The novel SPH model combines a system of non-linear density constraint conditions and the divergence-free ...
Comparisons of weakly compressible and truly incompressible algorithms for the SPH mesh free particle method
In the smoothed particle hydrodynamics (SPH) discretisation method for the Navier-Stokes equations the most widespread method to solve for pressure and mass conservation is the weakly compressible assumption (WCSPH). This includes hydraulics ...
A conservative SPH method for surfactant dynamics
In this paper, a Lagrangian particle method is proposed for the simulation of multiphase flows with surfactant. The model is based on the multiphase smoothed particle hydrodynamics (SPH) framework of Hu and Adams (2006) [1]. Surface-active agents (...
