1. VISUALIZATION OF THE BOUNDARY BETWEEN FLUIDS USING THE SPH METHOD AND THE MARCHING CUBES ALGORITHM / VISUALIZAÇÃO DA FRONTEIRA ENTRE FLUIDOS UTILIZANDO O MÉTODO SPH E O ALGORITMO DE MARCHING CUBES
In engineering and special effects for film and television, fluid modeling is frequently used to simulate natural phenomena, such as fire, explosions, smoke, water, and air. Basically, this modeling uses mesh-based methods, such as finite volumes and finite elements, or mesh-free methods based on particles, such as MPS and SPH. A common question among partic

2. Computational animation of fluid flow using SPH / Animação computacional de escoamento de fluidos utilizando o método SPH
Since the late 70s, there is a growing interest in physically-based simulations due to its increasing range of application. Among these simulations, we may highlight interaction between rigid, elastic, plastic and breakable bodies and also fluids. In this work, one of these phenomena, fluid flow, is simulated using a technique known as Smoothed Particle Hydr

3. A EQUAÇÃO DE POISSON E A DECOMPOSIÇÃO DE HELMHOLTZ-HODGE COM OPERADORES SPH / POISSON EQUATION AND THE HELMHOLTZ-HODGE DECOMPOSITION WITH SPH OPERATORS
A equação diferencial parcial de Poisson é de fundamental importância em várias áreas de pesquisa, dentre elas: matemática, física e engenharia. Para resolvê-la numericamente utilizam-se vários métodos, tais como os já tradicionais métodos das diferenças finitas e dos elementos finitos. Este trabalho propõe um método para resolver a equação

4. A COMPARATIVE ANALYSIS OF THE MAIN PARTICLE-BASED METHODS USED FOR FLOW SIMULATION / UMA ANÁLISE COMPARATIVA DOS PRINCIPAIS MÉTODOS BASEADOS EM PARTÍCULAS PARA SIMULAÇÃO DE ESCOAMENTOS
This work comprises a comparative study of the particle methods Moving Particle Semi-implicit (MPS) and Smoothed Particle Hydrodynamics (SPH) in terms of their efficiency and accuracy. The methods of Finite Volume and Volume of Fluid (VOF) were used as reference for determining the accuracy of the particle methods. The methods MPS and SPH were compared with

5. UMA ABORDAGEM LAGRANGEANA PARA SIMULAÇÃO DE ESCOAMENTOS DE FLUIDOS VISCOPLÁSTICOS E MULTIFÁSICOS / A LAGRANGIAN APPROACH FOR SIMULATING VISCOPLASTIC AND MULTIPHASE FLUIDS
In the last decade in Computer Graphics, they were development many techniques to simulate the behavior of objects such as rigid bodies, water, smoke, hair and cloth. While these techniques focus in simplifled physical models through monophase fluids or ideal solids, we propose new simulation techniques of viscoplastic and multiphase fluids based on a lagran

6. Fluid animation by cellular automata and particles systems / Animação de fluidos via autômatos celulares e sistemas de partículas
The past two decades showed a rapid growing of physically-based modeling of fluids for computer graphics applications. Techniques in the field of Computational Fluid Dynamics (CFD) have been applied for realistic fluid animation for virtual surgery simulators, computer games and visual effects. In this approach, since the equation is solved numerically the n
