Remeshing self overlapping mesh?

Question

So here's the object I am trying to remesh :

and, in sculpt mode, I am trying to smooth the edges where the rings are intersecting. (circled in red)

But heres a picture of how mesh looks like :

So I created this object by boolean union.

and as you can see the circled red area are inside the top ring, and does not intersect with the top ring surface where they meet.

In order to smooth out the intersection, I have to have vertex intersections.

How can I do this?

Things I have tried :

1. Remesh modifier & voxel remesh

It makes my final mesh too angulated, and cant figure out how to avoid this.

2. Quadriflow Remesh

Doesnt seem to remove the overlapping area.

Answer 1

You should work with less polygons. As you'll have 5 torus, maybe create a 40 Major Segments/10 Minor Segments torus at the beginning so that you'll easily rotate them 72° later. Rotate it vertically, cut vertically to keep a half, duplicate it 5 times and rotate 72° on Z. Booleans them, rework the topology a bit on 1 of the middle intersections and 1 of the top intersections to get this kind of result:

Then, delete 4/5 of the object and duplicate/rotate again, and at last merge by distance.
