Default 3 cylinders - why non sweepable bodies?

I would like to ask you why geometry presented below:

is not sweepable?
It consists of 3 cylinders, 1st one: diameter of 5e-04 m and height as well; 2nd: d of 1.6e-04 and the same h; 3rd the same as 1st one. It is the model of airflow through microchannel.
I have done it in many ways: as 3 cylinders one by another or 1 bigger cylinder substracted by a ring in the middle; as one body or as 3 bodies. No idea why it cannot be sweepable because it has regular shape with one axis. The only way it is sweepable is when bodies are separated (not in one part in DM) but then mesh in one cylinder doesn't match to mesh in 2nd one.
I hope you can understand me clearly. If not I can share my project.
Thank you in advance for your help.

Best regards,

Some tips that i can give you.

- To use sweep method you can make all 3 cylinders as separate bodies and if you want the mesh connection you can use node merge feature under Meshing.
- The reason why you can't sweep your geometry could be that you have face imprints of the middle cylinder on other bodies. To check this you can hide the middle cylinder and look at the contact surface location.
- One unite body won't work because the geometry is not uniform. Ansys meshing can't handle sweep method that way.
- You can use multizone feature to mesh your geometry.

Hope it helps,

I am trying to make this body sweepable ( )

What I do is:

- slicing the two lateral cylinders --> which become sweepable
- slicing the bottom part, i.e. restriction + bottom cylinder --> which become sweepable
- slicing the hemisphere and the centrale part separately BUT they don't become sweepable in any way.

Any help would be much appreciated
