It can effectively improve the real-time performance of the algorithm while maintaining sufficient accuracy.īa, K., & Gakwaya, A. Finally, the method of pre-computed smoothing kernel functions is used to accelerate the proposed SPH model. Compared to the modern Smoothed Particle Hydrodynamic (SPH) solvers, the new SPH framework allows better incompressibility and similar convergence.
Then the divergence-free state increases the stability significantly and reduces the number of solver iterations. In the new framework, the position of particles is firstly modified by solving the density constraints, and the distribution of particles is adjusted to keep the density of fluid in a relatively constant state.
The novel SPH model combines a system of non-linear density constraint conditions and the divergence-free velocity field condition to enforce fluid incompressibility. In this paper, a novel, incompressible fluid simulation framework based on the divergence-free Smoothed Particle Hydrodynamics model is presented.
