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. WebSep 17, 2024 · The implementation first computes the density of each particle using the typical SPH approach with a cubic kernel. This density is then evaluated or mapped onto a sparse grid using spatial hashing in the support radius of each particle. This implies that memory is only allocated in areas where the fluid density is non-zero.
