Hi,

Does anyone know how to create an hexa mesh in a circular Y-junction in ANSYS meshing? I tried multizone, but if fails...

Regards.

The best way is to use ICEM, there are a lot of topics explaining the procedure step by step to generate a hexa mesh in a T/Y-junction.

3. delete two blocks on right and left of the small pipe
4. Make associations
5. snap vertices.
6. make o-grid inside the small small upto the large pipe's bottom. Select two extreme faces.
7. Make the O-grid for the larger pipe and again select the respective end faces.
8. go to edge mesh parameters and update all sizes and go to second tab and give size 2 and apply. Keep on applying until mesh size is at-least 20000 hexas
9.Check premesh.
10. One horizontal split in the large pipe.
11. Play with vertices location panel to adjust the blocking to higher quality.
