The Smoothed Particles Hydrodynamics method
In high performance computing, most of the focus is on grid based methods, computed exclusively by CPUs. However, mesh-free method can be a viable alternative depending on the situation, and it is even more the case when the computing can be helped by GPUs. The Smoothed Particles Hydrodynamics (SPH) is one of these methods, and also the most widely established mesh-free method. It is particularly used in the fields of astrophysics, solid mechanics, and fluid dynamics.
In this presentation, we will introduce the SPH method, observe the results given for the example of a dam break, and the speedup obtained by computing on a GPU in addition to the CPU, using the DualSPHysics code.
