Good Day All,

I am attempting to combine an EM simulation with a circuital simulation in CST Studio Suite, which I am new to (up until now I have been a FEKO user).

What I am having trouble with is the discrete port setup. As a hypothetical example, say I wanted to inject a current into the object in the first image (which is entirely composed of a PEC medium) and review the radiated EM fields. I would expect Port 1 to have two connections - i.e. a positive and a negative - where I could connect a current source to in the Schematic view.

When switching to the schematic view, however, I only spot a single connection, as shown in the second attached image.

How would one go about ensuring that two connections would appear in the schematic view?

Kind regards,

K
