Association of blocks and vertices in ICEM
 

Hi people,
I am trying to mesh a separator which is actually a combination of joined cylinders. I have a problem, as showed in the pictures, with this small pipe around which I have to generate mesh. I really don't know the solution, I attached the blocking and associations of the blocks but I am not sure if this is the right approach.
Can you make in ICEM these "guidelines" for mesh around circular object, because as now, when I have a circular object inside of another circle and it not in the centre then, when it come to ICEM, I am pretty lost.
I would use any kind of advice. THANKS!
