NSE would cause lot of trouble during the mixture procedure of the water flow and the waves in lower left corner (two-phase transition with "air" or whatever obove)
Definitely not using NSEs... it looks a lot like Blender which uses (last I checked) the Lattice-Boltzmann Method... I don't think the poster is claiming that this IS an NSE simulation though, just the title of this particular work...
@shinWangXiao LBM is a discrete method of evolving the state of a fluid using NSE. It's not one or the other. LBM, SPH, FD, FEM, and many other methods allow people to find the evolution of a fluid over time. LBM is derived through a multi-scale expansion of the NSE.
@jojodi I suppose it would be better, then, to say that I have a preference for the MAC grid and tetrahedral discretizations? I always thought that LBM solves the Boltzmann Equation, not the NSE, and although one may be derived from the other, I've always considered them mathematically (if not conceptually) distinct...
The flow you show has seperation. I thought that once seperation occurs you can no longer rely on the Navier-Stokes equations.

Looks great, though : )

sorry, but this animation wasn´t done solving the NS equations, right?

yes, indirectly, it was done solving the NS equations.
