How do I determine the terminal width for a calibration group?
Geometry Elements - Co-calibrated Internal Port Calibration Groups
Terminal width is the electrical contact width of the element which will be connected outside the Sonnet environment. Entering a terminal width allows you to accurately model the current flow from the circuit geometry into the element. The terminal width is selected in the Calibration Group Properties dialog box. For more information, click on the appropriate link.
This sets your terminal width to match the length of the polygon edge to which the co-calibrated port is attached. This option should be used when there is only one co-calibrated port on a polygon edge and the polygon edge is not significantly larger than the element which will be inserted using these ports. Look in the co-calibrated port assistant for an illustration of a correct feedline.

This sets your terminal width to the smallest possible size of one cell wide.

This option allows you to enter a known electrical contact width.
