An improved particle packing algorithm for complex geometries in SPH

by   Pawan Negi, et al.

Accurate simulation of fluid flow in the presence of complex geometries with mesh-free methods requires that the geometry surfaces be captured accurately with particles. The traditional ways to do this with particles do not result in an accurate representation of the geometry surfaces. In this paper we propose a simple SPH-based algorithm to produce homogeneous particle distributions that capture the geometry surfaces accurately in two and three dimensions. Several benchmark problems are solved to demonstrate the accuracy of the new algorithm. The algorithm is open source and our manuscript is fully reproducible.
