How to active volume velocity with separate emitter

[saiyawong 0]

Hi guys,

I'm wonder how to active volume vel with just some emitter or just on some volume source.

Example; I have a water in the glass. I want to swirl the water, So I create vel field for that and use to volume vel by copy in operation mode(have image). So now my water in the glass is swiling.

And then, I want to put some red juice to the glass while water is swirling. The red juice will be go downward and swirl follow the water.

The problem is!!! ... When I emit my red juice to the glass, the volume vel have effect and active to my red juice too. that wrong, I don't want that .

So how can I active volume vel just only with flip souce1(Or water in my example) and not active on the flip source2(or red juice on my example)?

Thanks for every reply.
