Displaying Node Names, Tags, and Types in the Model Builder
Selecting the Model Builder Node Contents
The Model Builder always shows the label for the nodes. To add more information, in the Model Builder toolbar click Model Builder Node Text . Then select any combination of options from the list: Name, Tag, and Type. See Figure 3-5 for examples.
•
A Name is only used in the Model Builder for short names (descriptions) of the nodes. The Name can only be changed for the top Component, physics interface nodes and multiphysics couplings, and for Definitions nodes. Some Settings windows have the option to change the Name. See Settings and Properties Windows for Feature Nodes for information about Label versus Name. The Name and Tag for top level features are often the same.
For Definitions features, the Name is displayed differently for Functions, Probes, Nonlocal Couplings, and Pairs. See Common Settings for the Definitions Nodes for more information.
•
A Tag is unique for each node and is assigned automatically. Tags are primarily used when running COMSOL models in Java or MATLAB. Select Tag to display each node’s feature name with the predefined tag in curly braces using an italic font. The Name and Tag can be the same.
•
A Type is automatically assigned by the software and cannot be changed. Select Type to display each node’s feature type (predefined name). This is the most useful if a node Label is renamed or if you use a local language other than English and want to see the predefined name; otherwise, the type and the label are the same (except that the label typically includes a number, such as Boundary System 1).
Figure 3-5: Examples of the available combinations on the Model Builder Node Label menu. The second example of a Type shows how this is useful when the Label is edited in the Settings window and you need to know the original type of node.
Labels
Node Settings windows have a Label field where you can change the default node description for all levels (except the root node, which gets its name from the model filename). The label can also be changed by right-clicking and choosing Rename or by pressing F2.
The Label can also be displayed in the Model Builder where it is called a Tag. See Settings and Properties Windows for Feature Nodes.
