Tools => Add Component => User Model

You select Tools => Add Component => User Model in order to add a component to your geometry that is a model from a library purchased from another vendor, or developed in house. An assistant appears on your display which helps you set up your component. This dialog box is also opened when you select the command Modify => Component

Fields in which you may enter a variable instead of a constant value are identified with a drop down list, an example of which is pictured below. The list includes the entry <Add Variable> in addition to any existing parameters. Selecting <Add Variable> from the list opens the Add/Edit Variable dialog box to allow you to create the variable. If an existing variable is entered, then the entry <Edit Variable> appears in the list. Selecting this entry opens the Add/Edit Variable dialog box to allow you to edit the presently selected variable.

Note that directly typing in the name of a variable which is not yet defined, instead of selecting <Add Variable> from the drop list, also causes the Add/Edit Variable dialog box to appear when this dialog box is closed so that you can define the new variable.

For the User Model component type, the analysis engine, em, first performs an electromagnetic analysis on the geometry, and then uses circuit theory to connect the model to the geometry. This allows you to subsequently change the model used by your component without performing the electromagnetic analysis another time on your geometry.

Modelithics models are presently the only supported vendor, although it is possible to create custom models. If you are interested in doing so, please contact your Sonnet Software representative for details. Use of Modelithics models requires a license purchased from Modelithics, Inc in addition to your Sonnet license.

Note: The Component Assistant appears when you open this dialog box to help you set up the inputs for your component.

User Model:. You must click on the Browse button to open a window which allows you to browse through the model library and choose a model. Once you have selected a model, the model name is displayed in this dialog box. The model library opened by this command is defined by the path entered using the Admin => User Model Configuration command in the Sonnet task bar.

Parameters: Click on this button to open the Model Parameters dialog box which allows you to define the values of any parameters defined in the model. It is possible to use variables in your main project to define parameters in your model.

For a detailed discussion of Components, please refer to the "Components" chapter in the Sonnet User's Guide.
