Particle refining and coarsening method for smoothed particle hydrodynamics simulations
A particle refining and coarsening method for smoothed particle hydrodynamics is presented and applied to fluid mechanics. This method enables the particles to be refined or coarsened until a proper resolution of particle density for the geometry is achieved, which leads to a higher efficiency despite using a smaller number of particles in the whole simulation domain. The performance of this method is studied through some examples of shear cavities.
