I didn't quit understand the geometry. But this is blocking according to my perception.

just create your block without the extended part then extrude...

Ali, you have made it easy to understand the extrude and rotate in blocking and edit mesh tab.

Yes

Yes. For both I used default settings (offset = 1). Then made the association and snaped vertices. After that I used vertex command to align other parallel vertices. Then made second o-grid and splited block at the center where wall is located. Also I changed the material of unwanted blocks as void (used index control to select the appropriate blocks).

thank you Ali.

as i am using icem cfd interactive mood (i mean running icem in ansys meshing using multizone), so i do not have permission to modify the geometry.beause when i meshed in icem cfd, then in returing to ansys meshing there will be errors.

but the same circle is in your files, how did you create that? you did like Far?
