From time to time, I'm testing new ideas regarding fluid dynamics. This time at large scale, shown is an open water square field of 200x200 m. I used Blender's El'Beem free surface fluid simulation library. It is based on the lattice-Boltzmann method (LBM) and is able to perform physically accurate fluid simulations very efficiently. (Of course at this scale accuracy is degraded.) http://das-raster.de
