Interactive Physically-Based Modeling for Gaseous Object using Smoothed Particle Hydrodynamics

modelling the various kind of fluid based on Smoothed Particle Hydrodynamics (SPH) in modelling and simulating the gas flow with free surfaces. The modelling technique uses particle system together with molecular dynamics and also any possible external forces. The fluid equations previously used to model compressible fluid are now used to model incompressible fluid, the stiff gas, which is often used in Eulerian grid-based approach. In modelling stage, boundaries and obstacles are determined in order to make a real response of fluid with the boundaries. The leapfrog scheme is used to advance the fluid to the next state. However, the model still needs further modification to improve the realistic and simulation time, which is the goal of every simulator.
