Solid-fluid interaction with surface-tension-dominant contact

We propose a novel three-way coupling method to model the contact interaction between solid and fluid driven by strong surface tension. At heart of our physical is thin liquid membrane that simultaneously couples both volume rigid objects, facilitating accurate momentum transfer, collision processing, tension calculation. This implemented numerically under hybrid Eulerian-Lagrangian framework where modelled as simplicial mesh simulated on background Cartesian grid. devise monolithic solver solve interactions among three systems liquid, solid, membrane. demonstrate efficacy through an array rigid-fluid simulations dominated tension, which enables faithful modeling host new surface-tension-dominant phenomena including: objects with higher density than water can keep afloat top it; 'Cheerios effect' about floating do not normally float attract one another; weakening effect caused surface-active constituents.
