Comsol Error When compiling Equations

Please login with a confirmed email address before reporting spam

Hello, I am currently working on a project for my electromagnetics class where we have to design a low pass filter. I am trying to compute the frequency domain plot. When I try to compile I get the error "Uniform lumped ports should be placed between two conductive boundaries. Feature: lumped port 2 (lport2) Feature: lumped port 1 (lport1)". I am not sure how to fix this since I have the lumped ports between two conductive boundaries. I have attatched my project file and I would appreciate any help. Thank you, Nicole

Actually, your geometry is defective. Your ports are not properly connected to the other conductors, i.e., there are thin gaps. Zoom in on your geometry and take a closer look.
