hfss boundary conditions

Dear All

I'd like to understand better how and when apply the boundary conditions on a complex structure. I would like to have a doc or book focused on the boundary condition subject using an electromagnetic simulator in a piratical cases. Do anyone know if there are doc/book specified thought for electromagnetic simulators. I know, of course that there are a lot of book that explain the Maxwell equation and related boundary conditions, but applying them in real cases , or how to axprossimate the idea theoretical boundary conditions to piratical example could be a different story.

Best Regards
Paolo

Hi everyone
