Sph cubic kernel
WebThe advantages of SPH over standard grid based approaches can be summarised as follows: Firstly, SPH is conceptually both simple and beautiful. All of the equations can be derived self-consistently from physical principles with a few basic assumptions. As a result complex physics is relatively simple to incorporate.
