Tetrahedra mesh for "two cylinders"

Dear GiD-team,

I want to create "Tetrahedra mesh" for "Structure composed of two cylinders".
Moreover, I want to create "mesh reflecting cylindrical shape".
(that is, I want the mesh shape to be the same as two cylinders.)

Then, I defined the number of line divisions and mesh is generated.
In the vicinity of the line, the number of divisions is reflected.
However, the division number is not reflected in many parts.
And as a result, the mesh shape was different from that of the cylinder.

Would you give your advice?

Thank you.

You can set the laterals (4 sided) surfaces of the cylinders, to be meshed structured.
Mesh->Structured->Surfaces->Assign number of cells
and select the surfaces (but not the tops that cannot be structured)
It is not necessary to assign again number of divisions on each direction, your previous number of divisions are ok.

Note: the volume mesh of tetrahedra really won't be structured.

you will obtain this:
