Title:

    Improving Incompressible SPH Simulation Efficiency by Integrating Density-Invariant and Divergence-Free Conditions

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.
