| Abstract | In this paper, we present a refinement algorithm for the SPH method. A particle is refined by replacing it with smaller daughter particles. The position of the new particles is calculated by using a square pattern centered at the position of the refined particle. We study the possibility of scaling and rotating this pattern according to the local distribution of the particles to reduce the overlap with the newly created daughter particles. The results of the simulations using the fully refined domain and the simulations using the dynamic refinement starting from the unrefined domain are compared and are in a good agreement. Kinetic energy as well as linear and angular momentum are conserved by the refinement procedure. The algorithm is presented in 2D, but its extension to 3D is straightforward. |
