cylinder mesh in polar coordinates

I am trying to accomplish a simple task, e.g. generate a cylindrical polar coordinate mesh in z,r,theta. and have not had much success. I think it should not be THAT difficult and I would appreciate help.

Further question

I have the same or similar problem.
Are you trying to generate a structured mesh? Please, let me know if you do and if you have made any progress.
Thank you!

I have actually solved the problem by sweeping a quarter cylinder around the axis with manually mapped low (Theta = 0°) and high (Theta = 90°) faces. Afterwards (in Setup) rotational copy (original + 3) around the axis to make a full cylinder.

It is still a mesh in Cartesian coordinates :confused:

Here are a few screenshots to follow how to get to a cylindrical polar mesh. I meshed the core separately (2 Bodies) to avoid artifacts on the center line.

would u tell me how did you copy more to became a whole cylinder ?

thanks for answering so quickly , cfx setup or fluent ?
and would u say how ? i didnt know we can manipulate domain in setup ,

The thumbnails look like CFX. I don't remember the details though.
