Ghost SPH for Animating Water

This new approach to handling free-surface and solid-boundary conditions in SPH liquid simulations captures realistic cohesion for the first time and avoids the spurious numerical errors of previous approaches, via a narrow layer of carefully defined ghost particles in the air and solid.

Versatile Rigid-Fluid Coupling for Incompressible SPH

A novel boundary handling method for incompressible SPH that is applicable to both one-way and two-way fluid-rigid coupling. The approach avoids spatial and temporal discontinuities near the boundary, handles non-homogeneous boundary sampling, and allows interaction of fluid with non-manifold objects.

MultiFLIP for Energetic Two-Phase Fluid Simulation

Simulating fluid mixes like water and air by extending the FLIP method with two classes of particles and two grid-based velocity fields, capturing behaviour such as water glugging from a spout.

Animating Bubble Interactions in a Liquid Foam

By using a weighted Voronoi diagram to represent foam geometry, this particle-based algorithm efficiently generates bubbles and foams in liquid animation. It can produce miscellaneous behaviors, including foam structure under Plateau's laws, clusters formed by surface bubbles, bubble-liquid and bubble-solid coupling, bursting, and coalescing.
