Hello, I am trying to figure out how to simulate a very detailed swirling whirlpool. My houdini knowledge is not great and I so far all I've managed to simulate was a spinning mass of water in an even bigger mass of water…. which needless to say doesnt give a lot of detail to whirling.

This is what I am looking for:

It explains that they changed all the force vectors to point in a different direction and then warped the fluid mesh back to normal force conditions. I know a bit about VOP SOP an vectors but have no idea how to actually achieve this.

So far I have tried POP solver with FLIP fluid adding POP axis force, POP curve force, POP wind. Then tried adding noise field to gravity or POP solver but it did not create the swirls.

I am now thinking of advecting FLIP particles by a swirling smoke sim and see how that turns out.

Any advice would help loads. I feel like I am really close. I just need a swirling mesh and I can add splashes and mist from the angles of the mesh.
