Animate fluid injection

Hi there,

I am attempting to recreate the following effect:


in Blender. Blender doesn’t seem to handle animating fluid injections/fluid mixing very well - does anybody have any pointers?

Any help would be much appreciated. Many thanks in advance.

I think you could get this kind of effect with the smoke simulator.If you play with the different parameters I’m sure you could get something very close to this (gas and fluid behaviors are very similar in some situations).

The smoke simulator handles different smoke color mixing, but in your case, as you have one colored fluid and the other one transparent, you could just simulate one smoke and don’t bother with smoke mixing.

To make the smoke go down you can play with the density parameter, or just rotate 180° a regular elevating smoke.

Google Blender ink drop effect.
