Default Blocking

Mohankumarg12 is on a distinguished road
I am doing blocking for a part and my doubt is something similar to the example shown here.

If we have a sudden enlarged pipe like this we have to split the block to capture the bigger diameter and the smaller diameter and if we created a O-grid to get a good mesh, then at the enlarged section the quality of mesh is very poor.

If we create 3 or 4 O- grids inside to capture the features inside a cylindrical part then it will becomes much complicated and the quality is even worst.

Kindly any one help me how to solve this problem.

Thanks in advance.

BrolY will become famous soon enough
- Create a first O-grid for your global geometry
- Cut it at the jonction of your 2 tubes.
- Create another O-grid for your global geometry inside the first one to capture the small tube.
- Delete the blocks around your small tube.

You can do another o-grid inside the small tube to increase the quality
