Abstract:

Physics simulation has a wide range of applications such as medical simulation, training simulators, virtual prototyping, and computer animation for digital production - just to mention a few. In recent years particle-based simulation methods have become popular in the field of computer graphics since they have many advantages: they support topology changes, facilitate state transitions, such as melting or solidification, and allow a unified representation of solids and fluids which simplifies the coupling between the different physical models.

This presentation introduces the Lagrangian Smoothed Particle Hydrodynamics (SPH) approach. SPH is a spatial particle-based discretization method, commonly used for the numerical simulation of continuum mechanical problems such as the simulation of fluids, highly viscous materials, and deformable solids. Recent SPH simulation techniques enable to efficiently simulate large-scale scenarios with highly complex static and dynamic boundary geometries and to robustly handle interactions among various materials. Therefore, SPH is currently one of the most versatile tools for the simulation of fluids and solids.
