      Hi,

      i have to to mesh a hollow cylinder geometry ONLY with hexahedrons, i'm struggling in combining two transition zones (ratio 1:3) one perpendicular to the other, as in the small cube that connect the two outer transition layers intersecting, i cannot find a way to get only hexahedrons (see attached picture)

      How many elements are through the pipe wall thickness?

      Hi peter

      in the fine areas i do 0,35 mm elements with edge division, the wall is about 3 mm thick, so i do 9 divisions, the transition zones are 0,7 mm large

      What is the ID and OD of the pipe?  I will need some geometry to try it myself.

      What version of ANSYS are you using?

      Hi Peter

      thanks for the help, tomorrow i'll provide you the info, i don't have the proj. with me right now

      the latest 22 R2... but i'm not 100% sure, i have to check

      Here is a surface mesh that uses only quad elements to transition from 1:3 elements.

      Shell elements can be Pulled into hex elements using the Pull tool.
