It was long to find a good setting. The best results for quality and speed I
succeed to have was in 1 pass with a low error_bound (at .8) and a count of
200.

At the start, I read a paper of Jos Stam named "Stable Fluids" which
describe how to code in 2D a smoke animation program (if you make a web
search for "Stam Stable Fluids", you should find articles and source code).
I play with it and extend it to 3D. It was quite easy. I attach one of my
first results in DIVX format (don't look to much to the quality, it was
rendered with my own raytracer program).
The step to go to liquid motion was much more difficult. At the start, I
used mainly the paper of Nick Foster (http://www.cis.upenn.edu/~fostern/).
On the home page of Ron Fedkiw, the interesting papers are those of Frank
Losasso (for the octree idea) and Doug Enright (for the use of particules
to improve precision).
