Analysis Supported SPH Fluid Simulation


Smoothed Particle Hydrodynamics (SPH) is a mesh-free method that has been widely used in several fields such as astrophysics, solids mechanics and fluid dynamics. This computational fluid dynamics model has been extensively studied and is mature enough to enable detailed quantitative comparisons with laboratory experiments. Therefore, understanding and revealing the underneath behaviors of SPH fluid simulation becomes more meaningful when we are trying to understand similar phenomena in the real world. In the thesis, we use Finite Time Lyapunov Exponent (FTLE) along with other analysis methods to analyze the SPH. Since the data sets are mesh-free rather than mesh-based, we also change the traditional FTLE computation formula, and use Moving Least Square method to compute the stretching of each point. Then, we show the comparisons between our method and traditional method. In addition, we demonstrate how to utilize these analysis results to improve rendering of SPH simulations.
