Opening a Local Database
You can add an already created database to the COMSOL Desktop. This is useful, for example, if you want to move a local database created on another computer to your current computer or if you want to restore a database whose database directory has previously been backed up by external backup software.
From the Open dialog box, browse to and choose the SQLite® database file for the database you want to add. Click the Open button to add the database.
Model Manager will check that it can connect to the SQLite® database file, as well as check that the resources directory and the indexes directory for the database, as described in A Local Database on the File System, are found next to the SQLite® database file. If the indexes directory cannot be found, Model Manager will recreate the directory and its file contents using the data stored in the SQLite® database file. If all checks succeed, the Model Manager database is added to the COMSOL Desktop. Otherwise, the Open Local Database window is shown.
1
Write the path to the SQLite® database file under Database file.
2
Write the path to the resources directory under Resources directory.
3
Write the path to the indexes directory under Search indexes directory.
4
Write a label for the database under Label.
5
Click the Add Database button () to add the database to the COMSOL Desktop.
Adding a database stored on a network or cloud drive is not supported and COMSOL Multiphysics will report an error if it detects such a file system path. This includes placing the database in a local folder on your computer that is mapped to an external cloud drive via two-way synchronization. For more information, see https://www.comsol.com/support/knowledgebase/1295.
Opening a Local Database from Multiple COMSOL Multiphysics Processes
You can access the same local database from multiple COMSOL Multiphysics program sessions as long as these program sessions run on the same computer that stores the database. There are, however, a few caveats to keep in mind:
•
Changes saved from one COMSOL Multiphysics program session may not be immediately visible to other program sessions.
•
Some advanced search and filter functionality, as described in Searching and Filtering, will only be available to the first program session that connects to the local database. Other program sessions use a simplified search.
Connecting to a local database from multiple COMSOL Multiphysics program sessions running on different computers by, for example, trying to place the local database on a network drive or a cloud drive, or use some other type of sharing or synchronization tool is not supported.
Use a server database accessed via a Model Manager server when working in a multiple-user or multiple-computer environment.
