The Root Properties Window
To access the Properties window, right-click the root node and choose Properties from the context menu.
You can change a filename by saving the file, but the root node Name (root) cannot be changed for this top level node. This is different than for other nodes in the tree, where the name can be edited. See Displaying Node Names, Tags, and Types in the Model Builder for information. Also see Settings and Properties Windows for Feature Nodes.
The Node Properties section contains the following information:
•
 File or Database: If the model or app is saved to a file on disk: The file location where the file was saved. Also see Documentation and Application Libraries Root Directories. If the model is saved in a database: The database where it was saved. This field cannot be edited, but is automatically updated when the model or app is saved.
•
Saved in: Includes the version and build of the COMSOL Multiphysics instance that the model or app was saved in. This information is system generated.
•
 Created and Last modified: These sections cannot be edited and are automatically generated based on the computer system or network time and date settings.
•
 Saved with license: The license number of the installed software that the model or application was saved with is included here. Also see The About COMSOL Multiphysics Window.
•
 Application version: Enter a tracking version number for the model or application (for example, Internal Draft V1, Sales Demonstration V2, or Version B).
•
 Search path: Enter a file path to set a search path for external files. This path corresponds to model.modelPath(<path>) in the COMSOL Multiphysics API.
