Interacting Particles With Fluid

I have a project where I need a fluid to wash away some rigid bodies. I know this isn’t possible in Blender directly, but I was planning to fake it like this:

  • Bake the fluid
  • Simulate particles (using the molecular add-on) to “fill” my fluid object with particles.
  • I’d the simulate the objects that will get washed away as particles, and parent the objects to these particles individually.

But I can’t get anything to interact with the fluid mesh. Is there any way to make this possible? Or, have you got any better ideas for how to make a rigid body interact with fluid?

Thanks in advance!
