jbsmith162 is on a distinguished road
Using Ansys Fluent, I am simulating natural convection in a cylinder (d=3.127cm with aspect ratio = 5) and am trying to have a slightly denser mesh around the side wall and a much denser mesh at the top and bottom surfaces while keeping the internal elements larger (set at 2mm) with a goal of approximately 200,000 total elements.

I am able to add inflation and multizone features that extend the length of the temperature boundary layer from the top and bottom (2.09cm) and keep the inside elements at 2mm. The problem comes when I try to reduce the element length at the top or bottom or slightly along the side walls. I've found that face sizing reduces the size of all the elements and the face meshing doesn't do anything.

Are there any suggestion on how I can constrain the element size changes to just the outer surfaces and leave the internal elements at 2mm? I welcome and appreciate any insight/help.
