Trying to model microwave filter (superconducting). Need some ideas with steps for the mesh as nothing’s worked for me so far.

Hello
If you do a search using the work microwave using the link for "models and application library" you will get numerous hits that may help you along. Perhaps this could be a starting point

From what I saw in your model you do not have an airbox that surrounds your simulation so this is not helping. Look and read through many completed examples.
As for meshing, perhaps this would be a good case for a swept mesh. You could mesh the top layer of your traces using a triangular boundary mesh. You would then sweep that through the object. If you don't know what this means then look at some swept meshing files and video tutorials.

I have added the airbox. The mesh has been fairly done. But I get the Unifrom lumped port should be placed between two conductive boundaries - Feature: Lumped Port 2 & Lumped Port 1 when I run the study.
