Smoothed Particle Hydrodynamics numerical methods
This is a short course on Smoothed Particle Hydrodynamics (SPH) numerical schemes that will cover basic and theoretical concepts, as well as latest innovations. This course is primarily aimed at the beginners with a Master and/or a PhD degree in mathematics, engineering, computer science, physics, environmental disciplines, astrophysics and biomedicine, amongst others. The contents will also be of interest to post-doctoral fellows in academia and industry, as well as to academics and SPH practitioners.
The course will combine lectures on the basic theory and numerical methods.
It will also include a final tutorial using the open source code DualSPHysics, an international collaboration between five institutions: The University of Manchester (UK), The University of Vigo (Spain), Universitat Politècnica de Catalunya (Spain), University of Lisbon (Portugal), the University of Parma (Italy), and New Jersey Institute of Technology (United States): http://www.dual.sphysics.org
The SPH method
Developed originally for astrophysics, Smoothed Particle Hydrodynamics (SPH) has seen a rapid development in the last decade due to its application to engineering problems for both fluids and solids. The meshless and Lagrangian nature of SPH makes it perfect for applications where there are very large deformations with arbitrarily complex moving boundaries. The method is now attracting considerable interest from the industry for solving a range of complex problems where conventional Computational Fluid Dynamics (CFD) methods and Computational Mechanics have great difficulties.

Dr. Renato Vacondio is an SIR (Scientific independence of Young Researchers) Research Fellow at the University of Parma. He obtained his PhD from the University of Parma in Italy on SPH developing a new methodology for solving shallow water flows. His research focuses on the development of variable resolution for SPH including particle splitting and merging within DualSPHysics for the Navier-Stokes equations. He is a member of the Steering Committee of SPHERIC as well as the newsletter editor.
