AT LAST!!! This was a difficult birth like we say here.

I almost got the working steps from the pictures, but this took some time. The explanations were helpful.

I still don't get the difference, but thats ok. I will repeat that for different geometries and then i hopefully understand it.

Thanks for the kind help.

From what I understood, your mistake was to associate the o-grid you created in block 1 and 3 and associated the edges of those o-grids with the curves of the small tube. Because before that, you already associated the edges of the o-grid of bloc2 with the curves of the small tube.
So you have 2 edges for 1 curve, which is wrong. It created a 0-volume at the junction of the tubes.

I hope my explanations were clear ...

In addition to that there were duplicate blocks as well. Once I merge them and made the inner edges black (surface associated edges) problem was solved.

hi there, im trying to mesh a geometry very similar to this, the only difference being that the central pipe section is very short and behaves like an orifice. The steps are very clear in this post but could someone please further clarify step 6 please.
thanks in advance

Hi Tanjina,

I think you could try to do it but you need to split your geometry to get parts as O-grid topology approach. Take a look at this thread:
