You can import files that are not models into a database. Any file that is not recognized as a COMSOL Multiphysics file (that is, with the file extension mph) or a Physics Builder file (that is, with the file extension mphphb) is referred to as an auxiliary data file, or file (), in a Model Manager database.

Auxiliary data files are version controlled similarly as Models in the database. For example, when you import from the file system, a new file is created in the database with an associated first version. You can update an existing file in the database by selecting a file on the file system, and saving it as a new version from the File Settings window.

You may wonder why COMSOL Multiphysics simulation models and auxiliary data files are two different concepts in a Model Manager database, when they are all “just files” when stored on a file system. The main reason for the distinction is their respective storage characteristics and supported functionality. The known internal structure of a model enables efficient data reuse between versions, as well as searching deep within a model’s content using The Model Manager Search Syntax. An auxiliary data file is stored in the database as a chunk of binary or text data whose content is opaque to Model Manager.

The Settings window for a file shows settings for a specific version of the file. Update any of the settings and click the Save button () to save a new version of the file. You can write an optional save comment. Click OK to save.

This section displays a tree of all available Tags that can be set on the file, with the check boxes for the assigned tags selected. Click Clear Tags () to clear all selections. See also The Tag Tree.
