You can create and store multiple model databases on your computer, but you can have only one model database open at any time. Select FileNew from the main menu bar to create a new, empty model database. You can also click in the toolbar.

If you have made any changes to the current model database, ABAQUS/CAE asks if you want to save your changes before it closes the current model database and creates the new one. The new database then becomes the current database. To save the new model database, select FileSave from the main menu bar and enter the name of the database. After you save the model database, ABAQUS/CAE displays its name in the title bar of the main window.
