Using rigid body object as fluid in fluid sim

I’m creating a image of a chain melting, and used a rigid bodies to make the chain fall realistically, but now want to use a fluid sim to cause the last link to look like its melting. However I cant seem to be able to apply both the rigid body and fluid sim physics to the object. When I remove the rigid body properties the chain returns to its original position.

So is there is a way to finalize the simulation or convert it to a mesh which can be used for fluid sims?

You can bake a rigid body simulation to keyframes

You can duplicate any objects and swap a non fluid object to a fluid object at a particular frame. You don’t have to have one object used for multiple tasks
