Looking at the image in your first post, and reading about your need for a turbulence, here’s what I think you’re trying to achieve:
- Have the particles emitting from a rectangular shape
- Have the particles being affected by turbulence
- Keep the particles in place, so they don’t move up or fill the domain
Hope that I’ve got it right.
If that’s the case, I would create the emitter and the domain, also I would create a rectangular spline.
I think Mario Tran Phuc explained at the IBC that emitting from an object rather than the default x-particles emitter should give you a better result with more details.
I would change the particle direction to Y+.
Then, I would play with the domain settings, so maybe you need gaseous and reduce the particle speed.
If that’s not enough, you can always add a Gravity modifier, or speed or a combination of both.
Let me know if that helps.
