Monolithic Friction and Contact Handling for Rigid Bodies and Fluids Using SPH
(Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd., 2023) Probst, T.; Teschner, M.; Hauser, Helwig and Alliez, Pierre
We propose a novel monolithic pure SPH formulation to simulate fluids strongly coupled with rigid bodies. This includes fluid incompressibility, fluid–rigid interface handling and rigid–rigid contact handling with a viable implicit particle‐based dry friction formulation. The resulting global system is solved using a new accelerated solver implementation that outperforms existing fluid and coupled rigid–fluid simulation approaches. We compare results of our simulation method to analytical solutions, show performance evaluations of our solver and present a variety of new and challenging simulation scenarios.
