Saving Drafts of Models
To save a draft of the model opened in the COMSOL Desktop, go to the File menu and select Save Draft (). You can also press the keyboard shortcut Ctrl+S.
The Save Draft () option is only available if the model is opened from, or last saved to, a database.
The keyboard shortcut Ctrl+S either saves the current model to the file system, or as a draft in the database, depending on where the model was last saved. The file system is the default for unsaved models.
See also Example: Modeling Using Version Control for a tutorial that involves using a draft in the COMSOL modeling environment.
A draft model behaves in exactly the same way as a regular model in the database, except that a draft offers a streamlined way of saving it back as a new version of the model it originated from.
Working with a new draft model in the COMSOL Desktop typically involves these steps:
1
Open a regular model from a database.
2
From the File menu, select Save Draft (), or press Ctrl+S, to save a first version of a new draft of the opened model.
3
Work on the draft, intermittently selecting Save Draft () or pressing Ctrl+S to save additional draft versions.
4
From the File menu, select Save as Version (). Click Save () to save the opened draft as a new version of the original model. Click Save as New () to create a new model from the draft. See Saving Models to Databases.
You can also open an existing draft model from the Open window — perhaps in order to continue working on a draft created in a previous COMSOL Multiphysics program session.
