Merge in space claim and bonded contacts doesn’t work for chiral metamaterial

      I modeled a Chiral metamaterial cell in the space claim and considered that the surfaces are merge. However, in the compression analysis (Workbench), the circular surface is displaced from the other surfaces.

      Then, I considered bonded contacts between the surfaces and the same thing happened.

      The geometry has the following errors:

      But I don't know how to solve them. I divided the circular surface into two geometries and it didn't solve the problem.

      Can you help me, please?

      Thanks!

      Hi, You can split circular face at the edges of flat faces touching them. Then you can use share topology.

        Hi Kumbhar, 

         

        I solved the problem for shared topology and it presents the same problem. By clicking on zoom to fix, I was able to see the places where it reports that there is an error. See the image below, please. I checked and the surfaces are in contact
