FLIP fluid particles not separating despite opposing forces

[Dand]

Hi everyone, I'm trying to create a FLIP simulation where a fluid source is split into two parts: a blue top and a red bottom. My goal is to have them physically separate, with the red part falling away from the blue part.

However, the fluid stays connected and won't split.

 

• Blue source: force attribute set to (0, 0.1, 0)

• Red source: force attribute set to (0, -9.8, 0)

Even with these opposing forces, the drops remain stuck together. How can I achieve physical separation between these two colored regions within the same FLIP solver?

I tried various values for surface tension and viscosity.

 

I've attached my HIP file for reference. Thank you!

Just add This trick if you mean this effect @Dand, I Just add those nodes and Solver ..didn't change anything ,Have Fun

@Librarian

Thank you.

When I copied it exactly, it worked ！
However, it's difficult to understand. 
Could you explain the core concept behind how this separation is achieved?

I couldn't figure it out just by looking at the VOP, so I'd appreciate any hints on the underlying concept.

Just One question?? To you..
so that you can Answer your question Also. 

In your File, @border attribute , Please explain Usage of that attribute, purpose ???  

Thanx

@Librarian
I wanted to express the natural falling of half a drop from a large, plopping drop.

The @border attribute was just for trial and error to separate things. It has no special meaning...

• Test 1: I added horizontal noise to only @border inside the DOP.

• Test 2: I multiplied vertical v on only @border to make it accelerate original force node.
