SPH-Based Fluid Simulation for Special Effects
نویسندگان
چکیده
Simulating natural phenomena like smoke, sand or fluid by physics-based algorithms is a very complex and important task in the visual effects industry. Animating fluids is time-consuming and the result is hard to control. There are only a few commercial fluid simulators on the market, which fit the high expectations of the effect artists. Our goal is to develop a physically correct fluid simulation system using a particle-based approach which is very scalable and flexible for special purposes.

Combined DEM and SPH simulation of ball milling
A deeper understanding of the milling operation of ball mills helps mineral processing engineers to control and optimize them, and therefore, reduce their consuming power. In this work, the milling operation of ball mills is investigated using two methods, i.e. DEM and combined DEM-SPH. First, a pilot scale ball mill with no lifter is simulated by both methods. Then another pilot scale ball mil...
متن کاملReal-time fluid simulation with adaptive SPH
We present a new adaptive model for real-time fluid simulation based on Smoothed Particle Hydrodynamics (SPH) framework. Unlike traditional time-consuming SPH methods, our model can simulate fluid at a considerably faster speed without losing realism. In our model, we first introduce the non-uniform particle system and propose a generalized distance field function which considers not only geome...

Simulation of free surface flow and sudden wave profile are recognized as the most challenging problem in computational hydraulics. Several Eulerian/Lagrangian approaches and models can be implemented for simulating such phenomena in which the smoothed particle hydrodynamics method (SPH) is categorized as a proper candidate. The incompressible SPH (ISPH) method hires a precise incompressible hy...

متن کاملPresenting a Modified SPH Algorithm for Numerical Studies of Fluid-Structure Interaction Problems
A modified Smoothed Particle Hydrodynamics (SPH) method is proposed for fluid-structure interaction (FSI) problems especially, in cases which FSI is combined with solid-rigid contacts. In current work, the modification of the utilized SPH concerns on removing the artificial viscosities and the artificial stresses (which such terms are commonly used to eliminate the effects of tensile and numeri...
