I create O-Grid with selected blocks, delete blocks of pipe wall, then create another O-Grid for inner of small pipe, associate faces with surfaces for internal and external wall surface of a small tube and create O-Grid for big pipe. Any other ideas?

How to create the O-Grid for big pipe (or it had to be created from the start) and improve the quality (some bad cells)?

i tried adding them but it didn't work. i know what it feels like to do it all over again, so i redid the blocking for you without the external tube. What's left to do is extrude one face following the external tube and add another o-grid, sorry about that... other than that, the quality is ok.



Here is my try:

I didn't understand.
1. In your project I only click Pre-Mesh
2. I associate edges to...
3. ... curves.
4. I get the following.

i made the outer o-grid. there were some errors like some weird linkings etc....i fixed them.

you've to push some edges to improve quality, but blocking is ok now.
