1. Study of various numerical aspects of 3D-SPH for simulation of the dam break problem
Recently, the Smoothed Particle Hydrodynamics (SPH) method has been utilized as an effective tool for capturing details of the fluid flows. The Lagrangian nature of the SPH method facilitates the modeling of the free surface flows. In the present article, different numerical features of 3D-SPH are probed to find a set of options that can be used to achieve a

2. Uma nova abordagem numérica para a injeção de traçadores em reservatórios de petróleo / A new numerical approach for the injection of tracers in petroleum reservoirs
The injection of tracers are used in the investigation of ows in heterogeneous porous media, in studies related to the simulation of miscible dispacements in petroleum reservoirs and the dispersion of contaminants in aquifers. In this work we present new algorithms for the numerical approximation of tracer injection problems. We discuss recent developments o

3. Least squares and point-based surfaces: new perspectives and Applications / Minimos-quadrados e aproximação de superfície de pontos: novas perspectivas e aplicações
Surface reconstruction from unorganized points has been one of the most promising scientific research areas in Computer Graphics. In addition, it has been used successfully for the definition of fluid interface in numerical simulation of fluid flow. There are several reasons to that fact: for instance, considering Computer Graphics, we have the handling of o

4. A methodology and computational system for the simulation of fluid-structure interaction problem
In this paper a flexible finite element computational tool developed to investigate fluid-structure interaction applications in two dimensions is described. We consider problems which can be modelled as a viscous incompressible fluid flow and a rigid body-spring system interacting nonlinearly with each other. The coupling is dealt with the use of an interfac
