“…Undesired damping can also be introduced to the PBD framework too. To deal with this problem, the vorticity confinement method introduced by Fedkiw et al [2001] and extended by Hong et al [2008] and Lentine et al [2011] is adopted. The XSPH method [Monaghan 1989;Schechter and Bridson 2012] is also adopted to provide better particle distributions in the simulation.…”

Figure 1: Egg Mixture. In simulating the stirring of 3 eggs by a blender, the resulting simulation presents visually plausible mixing results. This mixing effect is achieved using our novel "extended mobility" formulation of the Navier-Stokes-Cahn-Hilliard Model. AbstractMultiple-fluid interaction is an interesting and common visual phenomenon we often observe. In this paper, we present an energybased Lagrangian method that expands the capability of existing multiple-fluid methods to handle various phenomena, such as extraction, partial dissolution, etc. Based on our user-adjusted Helmholtz free energy functions, the simulated fluid evolves from high-energy states to low-energy states, allowing flexible capture of various mixing and unmixing processes. We also extend the original Cahn-Hilliard equation to be better able to simulate complex fluid-fluid interaction and rich visual phenomena such as motionrelated mixing and position based pattern. Our approach is easily integrated with existing state-of-the-art smooth particle hydrodynamic (SPH) solvers and can be further implemented on top of the position based dynamics (PBD) method, improving the stability and incompressibility of the fluid during Lagrangian simulation under large time steps. Performance analysis shows that our method is at least 4 times faster than the state-of-the-art multiple-fluid method.Examples are provided to demonstrate the new capability and effectiveness of our approach.

“…Later work has yielded increasingly realistic behavior, and often used these models to add bubble details to traditional volumetric liquid simulations [Greenwood and House 2004;Hong et al 2008;Kim et al 2010;Busaryev et al 2012;Patkar et al 2013].…”

Figure 1: A variety of dynamic foam, film, and bubble scenarios captured by our method. Left: A small foam rearranges and settles to equilibrium. Center: A snapshot of an evolving catenoid soap film joining two circular wires, an instant before the film pinches apart. Right: A bubble with a wire constricting its mid-section gradually squeezes to one side. AbstractSimulating the delightful dynamics of soap films, bubbles, and foams has traditionally required the use of a fully three-dimensional manyphase Navier-Stokes solver, even though their visual appearance is completely dominated by the thin liquid surface. We depart from earlier work on soap bubbles and foams by noting that their dynamics are naturally described by a Lagrangian vortex sheet model in which circulation is the primary variable. This leads us to derive a novel circulation-preserving surface-only discretization of foam dynamics driven by surface tension on a non-manifold triangle mesh. We represent the surface using a mesh-based multimaterial surface tracker which supports complex bubble topology changes, and evolve the surface according to the ambient air flow induced by a scalar circulation field stored on the mesh. Surface tension forces give rise to a simple update rule for circulation, even at non-manifold Plateau borders, based on a discrete measure of signed scalar mean curvature. We further incorporate vertex constraints to enable the interaction of soap films with wires. The result is a method that is at once simple, robust, and efficient, yet able to capture an array of soap films behaviors including foam rearrangement, catenoid collapse, blowing bubbles, and double bubbles being pulled apart.

“…Hong et al . [HLYK08] proposed a hybrid SPH‐grid method that simulates the motion of water and air with a grid and the bubbling details with SPH particles. Chentanez and Müller [CM10] adopted the shallow water equation to simulate water in real‐time and utilized particles to capture the small scale features such as spray, splash, and foam.…”

This paper proposes a novel hybrid particle‐grid approach to liquid simulation, which uses the fluid‐implicit‐particle (FLIP) method to resolve the liquid motion and a grid‐based particle correction method to complement FLIP. The correction process addresses the high‐frequency errors in FLIP ensuring that the particles are properly distributed. The proposed approach enables the corrective procedure to avoid directly processing the particle relationships and supports flexible corrective forces. The proposed technique effectively and efficiently improves the distribution of the particles and therefore enhances the overall simulation quality. The experimental results confirm that the technique is able to conserve the liquid volume and to produce dynamic surface motions, thin liquid sheets, and smooth surfaces without disturbing artifacts such as bumpy noise.
