Smoothed particle hydrodynamics with adaptive spatial resolution (SPH-ASR) for free surface flows

A numerical method based on smoothed particle hydrodynamics with adaptive spatial resolution (SPH-ASR) was developed for simulating free surface flows. This can reduce the computational demands while maintaining accuracy. In this method, changes adaptively according to distance by splitting and merging. The particles are split refinement when they near surface, merged coarsening away from surface. search algorithm implemented identifying at shifting technique, considering variable smoothing length, introduced improve distribution. presented SPH-ASR validated various flows, results were compared those obtained using SPH uniform (USR) experimental data.
