In this lecture, we continue our SPH (Smoothed Particle Hydrodynamics) series by simulating the classic 2D dam break problem using the PySPH framework. The session focuses on the practical implementation of SPH simulations, with special emphasis on boundary condition handling using schemes. We start by walking through the structure of a PySPH application, explaining the role of key methods such as initialize, create_domain, create_particles, and create_scheme. Using the built-in dam break example, we demonstrate how to set up fluid and boundary particles, define physical parameters, and visualize the particle distribution. A major part of the lecture is dedicated to SPH schemes, particularly the EDAC scheme. You’ll learn: What a scheme is and why it is useful How equations and solvers are bundled inside schemes How schemes automatically manage particle properties How to configure solvers, kernels, steppers, and runtime options We then run the simulation in parallel using OpenMP, visualize results using the PySPH viewer, and export data for ParaView using XDMF. Finally, we cover post-processing, including comparison with benchmark results (Koshizuka & Oka), and dive deeper into boundary condition implementation, explaining how wall pressure and velocity are interpolated from fluid particles using SPH formulations (e.g., Adami-type boundary conditions).
