Thank you

What appears to be the problem?

It seems like you're on the right track from the attached image. Are you trying to create a Y-block in the intersection to achieve a fully hexahedral mesh?

Best wishes.

How to select faces to create Y block . I am a beginner of this ICEM CFD.
That is why I am struggling
How to do Y block This is my basic question?

[Crank-Shaft]

This is a basic outline -
a) Toolbar - Blocking>Edit Block>Modify Block Type
b) Set the drop-down menu "Set Type" to Y-block and select the one at the junction.

Additionally, there is an option to select the faces you want to exclude from this operation just below the drop-down menu.

Hope this helps.

Thank you for your kind help

Please find the attached geometry . . Is the blocking correct? is the quality of mesh is fine or low?
I am not sure . Kindly help

Thank you

Well yes it looks like you made the Y-block correctly and the splits also extend to the adjacent blocks, which is a good feature to have for sizing along the edges and to ensure that the blocks conform to each other.

Overall the mesh looks fine and you should be able to use metrics such as volume ratios/expansion ratios, aspect ratios, ortho. quality to determine the overall quality of the mesh. This falls under fairly fundamental knowledge of meshing and hence, there are plenty of resources out there to help.

Additionally, I would check that central part of the Y-block since I have a feeling your solver may have problems with that. Try to reduce the skewness and ensure that you check the sizing bias or growth rates along the edges.

Best wishes,
