Bottle filling from bottom to top

I have been asked to produce an animation of a bottle filling up with fluid. However, I don’t want to show fluid poured into the bottle - just the fluid swirling and rising up inside the bottle.

I setup a sim as follows:
Domain > Obstacle (bottle) > Outflow (at base of bottle) > Fluid (at base of bottle)

But when I bake it, I get nothing showing.

Any suggestions greatly appreciated.

First, you need an inflow, not an outflow to fill something :smiley:
Other than that, fluidsim is my archenemy in Blender. Never does what I want.
I am as grand as you in producing nothing after a long bake ^^
