Houdini - Mixing Fluids

Work in Progress - I am currently exploring mixing fluids and buoyancy in my current Houdini FX project. The container is a simple revolve and the ice cubes were created using a heightfield noise.

The primary challenge I am working through is the loss of simulated particles during the mixing process. I have been looking for a balance between particle spacing, and density that will create a realistic looking mix/swirl.

Another challenge I will need to explore next is finding ideal density and friction for the ice cubes to move naturally within the glass.
