Geometry Parts Saved in Databases
You can version control geometry parts in a Model Manager database by saving the corresponding model containing the part via, for example, the Save window — much like you would save any other model to a database. Model Manager will automatically detect if a saved model version contains any reusable geometry parts and, if so, store associated metadata in the database. This enables you, for example, to easily find such model versions by applying a Part filter when searching in the database.
If you load a part stored in a database into the model opened in the COMSOL Desktop and then save the model to the same database as the part, Model Manager will store an explicit reference link between the saved version and the part’s version. This helps you to keep track of, for example, which models are currently using a particular part, as well as preventing the part from being permanently deleted — see Reference-tracking in Model Manager for further details.
