Mesh Periodicity Question

  Hello, thanks for looking at this, I have a question about meshing in ICEM CFD.
  
  I looked through the documentation, and I think ICEM CFD can do what I want. My problem is when I tried to follow the directions, I got something incorrect, so I'm not sure of the exact process.
  
  What I want to do is create a mesh of a relatively simple shape, with the surface faces on the top and bottom having an identical geometry. I don't care in that regard whether its tri's or quads, but the mesh on the top and bottom needs to be identical.
  
  I have a figure I will attach to show this process.
  
  What I did was try to enforce periodicity by angle, because since those surfaces are parallel I thought it would be the easiest option. I then meshed with octree meshing, and although the meshes were similar on the top and bottom I still had some problems around the edges.
  
  Can you offer some advice on how I can get those surfaces to have identical meshes?

  Without holes inside your geometry, I am getting similar mesh on both top and bottom surfaces for default mesh setting. I did it in ANSYS meshing.

  A pictorial representation of the geometry would very useful, however as you mention that its a "relatively simple geometry", you can easily create a hexa mesh in ICEM CFD that would be identical on the top and the bottom surface. Even Ansys meshing can be used to create what you are aiming for as Vishal mentioned.
