HFSS15: Manually Assigning Terminals

If you want a terminal assignment to include multiple geometry selections, you must assign it as a Single Terminal. Terminals can be defined only after ports are defined. When defining terminals for a particular port, the right click menu for the port in the project tree has Assign Terminal.

To define a terminal explicitly:

1. Select the face(s) and/or edge(s) that contact the port and which define the terminal. All geometries to be used as the assignment for a terminal should be connected.

2. Assign as an excitation in the modeler window via right mouse click to display the shortcut menu and select Assign Excitation>Terminal, or on the Project tree, select Excitations and right click to display the shortcut menu and select Assign>Single Terminal, or from the menu bar select HFSS>Excitations>Assign>Terminal or HFSS-IE>Excitations>Assign>Terminal.

As a convenience, you can define multiple terminals with a single selection entity per assignment (or a single terminal with just one selection entity) via Assign Excitation >Terminal or Excitations >Assign>Terminal.

Terminals should be completely contained inside or on the perimeter of their ports. Set up terminal definitions as long as they contact the port in some way. The solver uses a mesh based test to verify that the number of terminals on a port is equal to the number of distinct conductors minus one.

3. Unless the Post Processing tab selection for the Port is set to Do Not Renormalize, you can set a Resistance value and units for the Terminal Renormalizing Impedence. This value can also be set at the port level, or for all excitations by using the Set Terminal Renormalizing Impedance command.
