Hi,
I tested different scheme (sweep+map, submap, etc) but always leading to bad elements quality: how would you proceed?
Thanks for your advices

No
I missed it when I made the model using FreeCAD 
Except if I’m mistaken, the part should be identical to:

Brick x 40 y 50 z 100
Brick x 50 y 50 z 100
Volume 2 move y 20 z 10
subtract volume 2 from volume 1
Brick x 50 y 50 z 100
Volume 3 move x 35 z 10
subtract volume 3 from volume 1
modify curve 50 blend radius 10
modify curve 54 blend radius 30
volume all copy reflect origin -20. 0. 0. direction -1. 0. 0.
imprint all
merge all
You could try to do a inside out mesh on the part with the tangencies.
First you would need to do decompose the troublesome part. Afterwards you can composite some surfaces and take control of the sweep directions and meshing order.

interesting cuts, however I need to keep “as it stands” the common edge betwwen the 2 fillets
(that’s why I tested first a sweep following the picture)
Something like this?

Surface 37 Vertex 14 Type side
#Draw Surface all Vertex Type
vol all size 2
mesh volume 1 2
quality volume all scaled jacobian global draw mesh
But as you see the quality is worse then with the first approach.
agree, that’s typically what I’m facing; I feel the solution is a mix of webcuts (complex?) and smoothing (that’s the challenge 
)
Thanks for you time
Paul
you could also try to cut the sharp tangenicies.
