Mesh Sizing Assistance Needed

      Hello there,
      I am facing difficulties in controlling the mesh sizing within my geometry in ANSYS 2023.
       
      The goal here is to set the mesh size to 1 mm on the mid-surface and 1 cm on the other surfaces. However, when I attempt to configure these settings using the mesh sizing options, the mesh size of the other geometry surfaces is reduced automatically to much less than 1 cm, rather than applying the specific sizes to the designated surfaces. This result led to have a huge number of nodes and consequently leads to a significant numerical effort.
       
      Here are the steps I followed:
       
      1. I used the mesh sizing option to set the mid-surface to 1 mm.
      2. I then set the other surfaces to 1 cm.
      Despite this, the software reduces the mesh size uniformly across all surfaces, rather than maintaining the distinct sizes as intended.
      Could you please provide guidance on how to properly set the mesh sizes to achieve my desired configuration (1 cm for mid surface and 1 mm for other sufaces)? 
       
      Thank you

      Hi Badr 

      Instead of using face sizing, use body sizing. For that, you need three separate regions with shared topology. You can split this domain into three regions and use shared topology.

      Now assign body sizing for the center object and use 1mm. Now in the global mesh settings, use a size of 1cm. So now th other two regions will use the mesh size of the global mesh setting and the center object will use the size of the body sizing.

      Thanks

        Thank you for your valuable support, find the result of separating the body into three regions with shared topology in the attached two pic's. It was a good result to reduce the number of nodes, but I would appreciate of you can guied me in making the mid-surface size 1 mm instead of makeing the whole mid-body size 1mm.
