The FLIP Fluids addon is a tool that helps you set up, run, and render high quality liquid fluid effects all within Blender, the free and open source 3D creation suite.
A variance parameter will randomize the Drag/Buoyancy coefficients in the FLIP Fluid Whitewater Panel. This will give the effect of bubbles having a varying size in the domain which could create a more natural looking simulation.
Although the variance parameters are not exposed to the UI, this feature was implemented into FLIP Fluids 1.0.8 (Mar 02 2020). The variance is automatically set internally.
