Solid-Fluid Interaction with Surface-Tension-Dominant Contact

Check out this novel three-way method to model the contact interaction between solid and fluid, driven by strong surface tension.

Liangwang Ruan, Jinyuan Liu, Bo Zhu, Shinjiro Sueda, Bin Wang, and Baoquan Chen presented a novel three-way coupling method to model the contact interaction between solid and fluid at SIGGRAPH 2021. At the heart of their physical model is a thin liquid membrane that simultaneously couples to both the liquid volume and the rigid objects, facilitating accurate momentum transfer, collision processing, and surface tension calculation. 

This model is implemented numerically under a hybrid Eulerian-Lagrangian framework where the membrane is modeled as a simplicial mesh and the liquid volume is simulated on a background Cartesian grid.
