Hello

This is a very simplified question and I need help to understand it.
a straightforward scene, a tube, a container ... almost default.

when the transform node is at its origin, I see particles moving with the ocean spectrum. but when I move the tube up the particles disappear.
this is what I understand when the domain is going up ( and the waterline option is off) the source is coming from 4th input where It gets its transform from tr3. In other words, everything should work, but they don't.
what am I doing wrong?

I appreciate any help you can provide.

apparently, when the waterline option in Flipsolver is off, the water level is at Y=0 by default.

It is reasonable to think that when I move the domain up ( Y+), the ocean evaluates which is connected to it, moves up then Flipsolver solves the simulation wherever the water is, but that doesn't occur here.
