Y blocking and O grid

Dear all Please find the attached geometry
I did Y blocking and O grid operation . I am not sure what I am doing is correct or not? Please help me If I made a mistake in my model
The ogrid created along the edge is not satisfied it is (/) upward direction . I think it should be (\) like this. I am new to this software I struggling Please help me

I am curious as to why you tried to create the O-grid along each of the branches.

I personally would've tried to just use 'Index Control' and then split along the central line along each branch. This can simply be done by extending the splits from the Y-grid at the intersection.

This would still result in hexahedral cells over the entire domain without the additional O-grids that you included.

My 2 cents.

Dear Crank shaft
If I didnot do the O grid operation the mesh pattern is some like in the picture
