Hi,
I suppose that your port is a waveguide port... and then the CST meshing need to have 3 meshcells free (no PEC!) to calculate mode, impedance...
that means that you have metal or other PEC in this area of the port.
Then check your port excitation, background properties and boundary conditions !
Other solution, if that is not coaxial port, you can use the discret port...
What is your model exactly ?
