Adding S-Parameters Directly in HFSS for Single-Port and Multi-Terminal Models

S-parameters can be added directly in HFSS for a single-port model or a multi-terminal model. First, create a circuit port by selecting the edges where it should be defined. Then, in the Project Manager, right-click on Circuit Elements > Create > Single-Port Model or Multi-Terminal Model. Once this is done, the Create N-port Circuit Element dialog will open, allowing selection of the Touchstone files to import.
