A novel unified particle-based method is proposed for real-time dissolution simulation that is fast, predictable, independent of sampling resolution, and visually plausible. The dissolution model is derived from collision theory and integrated into a smoothed particle hydrodynamics fluid solver. Dissolution occurs when a solute is submerged in solvent. Physical laws […]
Blue Noise Sampling using an SPH-based Method
We propose a novel algorithm for blue noise sampling inspired by the Smoothed Particle Hydrodynamics (SPH) method. SPH is a well-known method in fluid simulation — it computes particle distributions to minimize the internal pressure variance. We found that this results in sample points (i.e., particles) with a high quality […]
Fast multiple-fluid simulation using Helmholtz free energy
Multiple-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 […]
Energy-based dissolution simulation
We propose an energy-based method for dissolution simulation. Both the fluid (solvent) and solid (solute) are presented by particles. The dissolution priority of solute particles is based on the kinetic activation energy. The position of solute is determined using rigid body dynamics. We demonstrate plausible dissolving behaviours by using examples.
