COMSOL 6.3 - Editing Node Properties, Names, and Labels

Editing Node Properties, Names, and Labels

All nodes, except container nodes, have a common set of node properties, some of which can be changed and some system-generated properties that cannot be edited. The root node has additional information that provides an overview of the complete model file. The window for the root node also includes a section with additional information about the model file. The is set from the window for the root node. See The Root Settings Window for details about the root node.

Editing a Component Name for Use with Variables

Use a component Name to access variables throughout the model. The name is part of the full reference to variables (for example, when referring to variables in another model component). To edit a component name, in the , click a node. The window for a node opens. Edit the default (comp1, comp2, and so on) as required in the field.

Renaming a Node Label

To rename a node in the (except container nodes with fixed names such as under ), right-click a node and select (

) or press F2. Enter a and click . The is both updated in the and in the window.

The Node Properties Window

In the , right-click a node (except “container nodes” such as ) and select

from the context menu. The window for that specific node then opens next to the window. The node properties vary by node type.

Node Properties

This section contains these fields:

•

The field defaults to a system label for the node.

•

The field defaults to a system name for the node.

•

The is a unique system-defined tag for the node, which cannot be changed and is mainly used when using the COMSOL API and the optional LiveLink™ for MATLAB®.

•

The field is system generated and shows the node creation date and time.

•

The field contains the name of the author (creator) of the node. In addition to editing the author name manually, you can make a change for all nodes that you add later on based on the name in the field on the page in the The Preferences Window.

•

The and fields are empty by default. Enter version numbers or comments to track model changes or changes to specific node contents. For the comments, use the formatting options above and below the text field as desired. The entries in the field appear in a section in the window, if you have selected checkbox under in the dialog.

•

By default, if a node’s settings are described in a report or presentation, the comments you enter in the field are also included; see Node Properties for Reports and Presentations.

•

For nodes with settings that can be described in reports and presentations, toolbars with buttons that let you control the formatting of the text appear above and below the field; for details about these toolbar buttons and how to use them, see Text Formatting Tools.

Returning to the Settings Window

When you are finished editing the properties, right-click the node again and select to return to the window (or click another node and then click the node again).
