Lattice Pair on unequal conditions

  Hi,
  Here is my scheme:
  I need to define the boundary conditions (lattice pairs) for the side walls. As you can see, the shape of the top layer is different, which has led to errors in the matching boundary conditions. I would like to know how I can address this issue.
  I based this simulation on a shape described in a specific article.

  Hello Volter,
  
  We appreciate your reaching out to Ansys Learning Forum.
  
  At a first point of view, please, make sure that you are using a symmetrical structure. This aims to make the lattice pairs to "see" identical meshes.
  Secondly, we would appreciate the fact of pointing out the errors and/or the mesh feedback in order to had a more robust image.
  Since I am not 100% sure of the nature of the error that comes up, by experience, I would advice you to use the latest version (AEDT 24R2). Moreover, in 25R1 version, we have implemented a new approach leading to a flawless simulation considering the Lattice Pairs approach. Unfortunatelly, I am not able to provide an exact release date.
  
  I hope this helps!
  
  Kind regards,
  Jason.
