Common Settings for the Definitions Nodes

Many nodes that can be added under the node or a node at the Component level share the same settings or use settings generally found throughout COMSOL Multiphysics.

The following buttons are available in many of the windows and are mostly self-explanatory. These are not explicitly described or explained for every node.

•

In general, use the (

), (

), and (

) buttons and the fields under tables to edit the table contents. Or right-click a table cell and select , , or .

•

The button (

) under a list of named selections opens an dialog box that contains all existing selections for the same geometric entity level.

•

To save the contents of a table, click the button (

) and enter a in the dialog box, including the extension .txt. Click to the text file. The information is saved in space-separated columns in the same order as displayed on screen.

•

Use the button (

) and dialog box to import data in text files, generated by, for example, a spreadsheet program. You can also click the downward arrow beside the button and choose (

) to open the fullscreen window. Data must be separated by spaces or tabs (or be in a Microsoft Excel Workbook spreadsheet if the license includes LiveLink™ for Excel®).

	In editable table cells (in the settings windows for Parameters and Variables, for example), you can triple-click with the mouse to select all content

For , , and other matrix utility nodes, , and , you must specify a that is unique within the model component where the feature is added. You can use this Name in expressions, and it is also the node’s . A unique default is always generated when the node is created. See Settings and Properties Windows for Feature Nodes and Displaying Node Names, Tags, and Types in the Model Builder for more information.

For it provides a namespace for variables created by the coordinate system. The default is sys1. For example, the determinant of the coordinate system’s transformation matrix can typically be accessed in equations and postprocessing as sys1.detT. See the subnode for a complete list of available variables.

	To display the Equation View node under all nodes creating variables, click the Show More Options button () and select Equation View in the Show More Options dialog box. See also Equation View.

For all you must specify a that is unique on the global level or within the model component where the feature is added. You can use this function name or operator name in expressions, and it is also the node’s . A unique default function name or operator name is always generated when the node is created. See Functions.

For all you must specify a that is unique within the model component where the feature is added. You can use this Variable name in expressions, and it is also the node’s . A unique default Variable name is always generated when the node is created. See Probes.

For all you must specify an that is unique within the model component where the feature is added. You can use this Operator name in expressions, and it is also the node’s . A unique default Operator name is always generated when the node is created. See Nonlocal Couplings and Coupling Operators.

For all you must specify a that is unique within the model component where the feature is added. You can use this Pair name in expressions, and it is also the node’s . A unique default Pair name is always generated when the node is created. See Identity and Contact Pairs.
