Hello, Ansys community.

I am modelling a 3D liquid-liquid flow between two parallel plates using the VOF model. I'd like to generate droplets randomly at the inlet boundary rather than just patching them. Could you please assist which UDF I should use for my purpose?

So you want to inject random droplet into the domain from the inlet? You can think about using DEFINE_PROFILE or Fluent Expression to adjust the inlet boundary to inject some amount of the liquid phase then stop till the droplet has formed then inject again.
