New Local Database
To create a new local database on your computer:
1
Under Database name, write the name of the new database as stored on the file system.
The database name can only contain characters that are valid for a directory name and filename. The name will also be used as the initial label of the database in the COMSOL Desktop, although this label can later be changed — see Database Configurations.
2
Under Databases directory, write the path to the parent directory that will contain the new database. You can also keep the suggested, prefilled directory path.
The database itself will be created as a subdirectory inside this directory.
3
Click the Add Database button () to create the new database.
Creating a database on a network drive is not supported and COMSOL Multiphysics will report an error if it detects a path to such a file system.
The field under Databases directory contains a prefilled default directory path appropriate for the underlying operating system. You can change this default from the Preferences dialog box in the Databases directory field under Local databases on the Model Manager page.
A Local Database on the File System
The created database consists of a directory with the name specified by the Database name field, located within the parent directory specified by the field under Databases directory in the New Local Database window. This database directory contains:
•
An SQLite® database file with the same name as the directory. Its file extension is mphdb.
•
A resources directory containing files whose file sizes are deemed too large to store directly inside the SQLite® database file. These files can, for example, be built, computed, and plotted data generated by models, or auxiliary data files such as CAD and interpolation data.
•
An index directory containing files used by Model Manager for searching and filtering.
Local databases can be backed up using any regular backup software used for backing up the workstation. Make sure to include all files and directories: the SQLite® database file, the resources directory, and the index directory.
