CNPqFluid simulation using meshless methods has increasingly become a robust way to solve mechanics problems that require dealing with large deformations and has become very popular in many applications such as naval engineering, mechanical engineering, movies, and games. One of the main methods is the Smoothed Particle Hydrodynamics (SPH) which has the challenge of simulating fluid with different behaviors (multiphase, viscoelastic, viscoplastic, turbulent), and to render high visual quality results in real time. The main goals of this work are to investigate the following subjects: (a) the simulation of weakly compressible fluids using SPH for different behaviors, (b) the simulation of fluids in large scale and at interactive frame rates ...
