I was trying to make a fluid simulation following this tutorial but fluid settings were changed in blender 2.8 and I'm at a loss. I don't know how to break the fluid into small drips like in this video. It's just constant streams.

This what I want.. It's a three-second-long video:

My blend file.

  • $\begingroup$ just increase the resolution. If that doesn't help, pls provide blend file because you didn't show us any settings you have made (and no, not everybody wants to watch an 8 minute video just to prepare an answer to your question). $\endgroup$

  • $\begingroup$ @Chris Thanks for answering. I don't think changing the resolution is the solution. It is still a constant stream. Also, I have updated my question. A three-second video of the effect I want, and a .blend file. $\endgroup$

  • $\begingroup$ A setting for "Honey" or heavy oil, implies Viscosity. Yours is enabled, but is set to 0.0. $\endgroup$

  • $\begingroup$ Diffusion also has a "Honey" quickset -- yours appears to be the default $\endgroup$

  • $\begingroup$ @james_t I did both of these things already. Setting Viscosity higher and using honey preset. The liquid just wouldn't separate like in the video. It just becomes a big chunk of liquid falling very slowly. Maybe I need to increase resolution like a thousand or something? $\endgroup$

2.79

Quite interesting, this dripping works in 2.79 with just default setup :) In general it is not too much expected behaviour, but works great for your purpose.
So ... one way is to download 2.79 and Bake fluid there. Than Export as Alembic (.abc) file.

3.xx

Speaking to Blender 3 - behaviour is different, because it uses completely different fluid solver (Mantaflow).

The way I accomplished this result ...

  • Set Domain's > Field Weights > Gravity zero
  • Add Force Field > Force, Shape > Plane, Strength -0.6, enable Falloff > Max Distance with value that ends bellow Inflow object

enter image description here

Or you can try Particle System > Fluid and render as Object (Metaballs).


Notes to your blend file: Try to simplify your Inflow object, there is no a need to bevel edges for simulation and also don't use Dimension of this object 32 m since world scale matters the dimension define tally will affect result. Don't waste your computation power and time – scale domain object as small as possible.

  • $\begingroup$ Interesting, indeed I thought the clumping didn't seem natural without perhaps some other objects underneath as collisions to obstruct/gather particles. $\endgroup$

  • $\begingroup$ @james_t ... now I got something useful :) Probably too late, but it didn't let me a sleep. Idea for solution came from appearance in 2.79 where it looks like an inflow levitates and just a drops are leaking. So the trick here is zero gravity and Empty object as Force Field bellow an inflow object with Falloff > Max Distance up to the bottom part of the text, that attracts (catches) lower parts of liquid. $\endgroup$

  • $\begingroup$ "zero gravity and Empty object as Force Field bellow an inflow object with Falloff"! makes sense. $\endgroup$
