HFSS15: Auto Assign for Terminals

The HFSS menu lists the HFSS>Excitations>Auto Assign Terminals command. This command also appears on the shortcut menu when you right-click on Excitations, or on a single port in the Project tree.

To auto assign terminals:

1. Once one or more ports are defined, you can use the port or Excitation level commands to Auto Assign Terminals. (HFSS>Excitations>Auto Assign Terminals.)

For each port specified, all conductors contacting the port will be located and the Reference Conductors for Terminals dialog will display. This resizable dialog contains a table of available geometries that are Conducting Objects. The example shown includes four conductors.

If you check the Highlight selected conductors box, selecting any conductor in the table highlights it in the modeler window.

2. Set the terminal naming by selecting Use conductor name or Use Port object name.

Ports are named by appending the terminal name (the default name is T) to the specified conductor or port base name.

3. For each conductor, you can check the box in the Use as reference column to so designate it. All other conductors will be considered for terminal assignment.

4. Select OK to close the Reference Conductors for Terminals dialog.

All remaining conductors on each affected port will be used. HFSS will then generate terminal assignments, create the terminals, and associate the terminals with the correct port.

5. After you add new model objects or new port definitions, you can again Auto Assign Terminals to add new terminals where appropriate.

When you execute Auto Assign Terminals, the conducting faces on a port that touch each other are recognized as defining a single terminal, as are conducting edges that touch each other.
