Water simulation problem

Hi, I read YannL''s water lecture, and I decided to try and add water simulation to my engine based on the lecture. First, I added water movement using Navier Stokes equations. The result seems to be very odd. I captured a short movie from the engine showing the problem: http://demons.org.il/etus/LeEnProb.avi You need DivX to watch it. Do you have any idea what am I doing wrong? I''m not sure I''m doing something wrong, but it doesn''t look like good water flow simulation to me. In the movie, I apply 15 forces(magnitude 5.3f) in 15 different places on the water surface. Thanks, - Etus
