I am trying to create something like this:
http://vimeo.com/5855153 [vimeo.com]

Problem is, if I create a fluid sim from a simple sphere, then create a particle emitter from the sphere and create the advection (changed to “position” instead of velocity) my particles seem to stick to the fluid a bit, but then disperse…

What am I missing to get the particles to “stick” to the fluid?
Thanks for any help

You can use the Advect pop.

I'm using the the advect POP, they're flowing through the fluid, but not “sticking” to it. So imagine if it was a surface, I'd want the equivilent of “sticky points”.

Change the advection method on AdvectPOP to “Position”. This way particles will move adequately to fluid velocity.

Yeah I did that too (see original message). Am I missing anything else? Maybe it's a case of resolution, I'm doing this quite low to test it.

If nobody can think of anything off the top of their heads, I'll make another quick demo scene and upload it.

Thanks for all the suggestions so far!

Ah, sorry, I had to missed that part. As far as I know all is there, just make sure your smoke doesn't diffuse to fast in a sim. You could attach a test file, I'm sure some one will help you with that (I'm far from Houdini for a couple of days ).

Ok I'll check some stuff out and get back to you guys if I still hit troubles.
Thanks for all your help.
