Well, I am working at this fountain for a project of my university. As you can see in the images below the stream follows the path clashing with everyone step, going out from the top and falling down on the ground.

The question aimed to you is: what's the best strategy to obtain a realistic effect for this fountain? With Which kind of approach I've to proceed? I think... maybe I should to use many jet of particles (two for each step) but, for the foam of the water? and How can I make collide the particles with a surface?

Sorry for bad english and many thanks to all

You could simply use real footage of filmed water, mapped onto planes. That would be the easiest way.

yes that is a great solution, thanks for the reply. But do you think that I'll reach a good grade of realism? I concern about the thousand of little partlicles of water that makes noise clashing on the surface.
If you also have good tutorial you are welcome :)

The grade of realism depends on the lighting of your scene and the footage you selected. Thousands of particles can end up into crude rendertimes.

Here's a quick 'n' dirty made example for you, to get an idea of a possible approach with PFlow on this.

You could mix some different techniques, use pflow with a udeflector maybe wrap it with a blobmesh, you could add an atmospheric like Fumefx for some mist, fake some foam with the shader.

More realism would be to try a fluid simulator like realflow (great demo available) or glu3d.

Thanks for posting this problem again in a duplicate thread. I will suggest one more solution. Render out one of your little step thingies with a particle system. Only render the particles then place that particle system over your rendered geometry in layers. So render one particle system and in post use it 2 zillion times.
