  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)

  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?

  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.
