While working on my SPH and DEM solver I had an idea of a new way to
solve this that allows many more particles, and this is the first test.
It's not full SPH, it's not FLIP, it's something.... else :O)
It's still in a a very early stage, but it seems promising to me, no
foam yet for this one, I'll continue with it next week when I come back
from my holidays.
36 millions of particles, 300 frames, 1hour 30 minutes
