Blocking topology for bluff body corners
 

Hi,

Can anyone assist with blocking around the corners of this model? Also on making a Y-block on the surface? The images show the two locations. I've changed the the vertex locations at the corners to improve the elment quality but cannot see the ideal surface block arrangement. Attached are the ICEM files. I've not yet made on O-grid and I have only assigned a global element size. The CFD domain is small as this is a testcase on making the blocking.

Thanks in advance.
