Kadomain is a Blender addon built to manage several physics simulation domains within the same scene. Developed by Picto Filmo, it works on its own and also runs alongside the Kaboom and Kafire addons.
The addon lets you create a KaDomain, add a flow collection asset to it, and add effector or force field objects as assets. Fluid flows are managed by collection and effectors by object. You can display assets without disabling them in the viewport, adjust the fluid parameters and material parameters of the KaDomain, and import a baked KaDomain cache as a volume object.
Kadomain supports Blender versions 3.6 through 5.1 and has been used with the Cycles and Eevee render engines. It ships under the GPL license, comes with a documentation page for UI explanations, and a demo video is available.
