I would like to be able to repeat the animation many times in one scene. Fluid and gas solutions How to bake multiple fluid simulations in one scene? don't seem to work here
The FLIP Fluids addon does not support more than one domain in a .blend file at the moment. A workaround to have multiple simulation animations in a scene is to export the simulation to the Alembic format through File > Export > Alembic (.abc). Once exported, you can import the animated Alembic files back into your scene.
