Trying to recreate this viscous FLIP folding/buckling effect any advice?

Hi! I'm trying to recreate the FLIP simulation from this reference:

I'm especially trying to reproduce the way the black liquid folds and overlaps onto itself, creating those small visible layers/ridges (image 2).

My current result is shown in image 1. The general motion is getting close, but my fluid stays extremely smooth and basically turns into one continuous sheet/blob instead of creating those overlapping folds.

Current setup:

  • Viscosity: 400
  • Surface Tension: 5
  • Swirly Kernel
  • The emitter is animated from right to left across the cylinders.

I'm wondering what I'm missing to get that layered/folding behavior. Is it mainly related to viscosity, emitter speed, particle separation, surface tension, or something else in the FLIP Solver?

Any advice on how to achieve the viscous buckling/folding visible in the reference would be really appreciated!
