摘要：We present a particle-based method for realistically modeling the interaction of incompressible fluids with arbitrarily shaped solid boundaries. When dealing with static solids, previous meshless Lagrangian approaches either require uniform sampling of solid boundaries or suffer from unexpected side effects. Our method resolves these issues using a new boundary handling algorithm that represents the solid surface as a single layer of boundary particles with different influence factors. This technique can more efficiently handle arbitrarily shaped boundaries without the side effects of existing approaches, and produces more realistic simulation results. We further propose a new form of weighting kernel that corrects the fluid density estimations and avoids negative pressures at the free surface. We have demonstrated the robustness and effectiveness of our method with a range of scenarios.
