Hello,

I am getting tringular mesh error in this conformal array antenna model, two traingles are overlapping in the mesh when I copied patch and feed from the main structure, kindly see my attached model here, Can anybody fix this meshing error in this array?

Hi @sswh2 ,

In your model there are two surfaces that are touching each other but not Unioned. Select Union1 and Union2 and go to Construct>Union to allow mesh continuity.

This should resolve the overlapping mesh elements issue.
