I am new to ANSYS mesh and am now trying to generate structured hexahedral elements for the geometry as shown in the attached figure.  

I am using Workbench 2023 R3 and I have tried with the Multizone method. I used default settings but specified a face as a manual source (as shown in figure), however, I got the following error messages:

"MultiZone found free block in swept body."
"The current meshing options and settings cannot generate a mesh."

I understand I may need to slice the geometry into pieces but how I supposed to do it? I tried to change the free mesh type to 'Hexa core' but it just gave me too many elements with bad qualities.

Any suggestions would be appreciated.

Yours,
Yu

Hi Yu,

You can try the sweep method. If that does not work, then you can split the body in spaceclaim.

Hi Ankush,

Thanks for your reply. I managed to do it by slicing the geometry into more small pieces based on the post you suggested.
