  Hi guys;
  I have the below green 2D geometry (the first image) and want to create its mesh to be like the blue meshed shape following that (the 2nd image). The numbers on the sides of the meshed one are the number of divisions on the edges.
  Unfortunately, my meshing method (the 3rd screenshot) is not successful after applying it. The result of my meshing approach is the last image (the 4th screenshot).
  Would you please tell me where I am mistaken?
  Thank you very much in advance.

  you will need to use edge biasing.

  As an alternative check if you have access to ICEM CFD. It can do this job with relatively simple steps. There are many tutorials over the internet.

  Hi Kkanade & Alainislas and thanks for your responses.
  Kkanade, the model's edges are already biased.
  Alainislas, it's interesting. I didn't know about this module of ANSYS. I'll check it. Tnx.

  You have to make share topology in order to get conformal mesh between parts. Put all parts into one component and make share topology in space claim or in design modeler. (dm is better)

  Hi ibmb202;
  Thanks for your advice. Putting all parts in one component is the solution. I just split the geometry up and then it worked.
  Cheers.

  Much better. Check the cell size at the corner to make sure the aspect ratio is OK for flow separation.
