# smoothed-particle-hydrodynamics

A MATLAB implementation of the smoothed particle hydrodynamics based on the Philip Mocz's paper, in both CPU and GPU. 

By using a GPU, we can speed up the computation to about 10 times. Here, I am using the NVidia Tesla K20m. It is probably the cheapest Tesla card in second-hand markets. ;-)

A normal GPU also works.  

Please read Philip Mocz's paper here:  

https://pmocz.github.io/manuscripts/pmocz_sph.pdf  

Although the paper stated MATLAB implementation, I can only find the Python implementation in his Github repository:  

https://github.com/pmocz/sph-python

These are some examples in this repository:  

Example 1:  

Free-falling Universitas Telkom's logo

Example 2:  

Free-falling particles arranged in a grid formation

Example 3:  

More free-falling particles also arranged in a grid formation  ;-)

Example 4:  

Waaayy more free-falling particles also arranged in a grid formation  ;-) ;-)

Additional notes:

SPHDemo2D_Ex2_NeighbourSearch_CPU.m uses a very simple neighbour search mechanism to reduce the execution time. We first sort all nodes based on their distances to the origin. Hence, the adjacent nodes are neighbours.
