Select File
Save from the main menu bar or click 
in the File toolbar to save the current model database, if it is new, or to append changes made during the current session to a previously saved model database. After you save the model database, Abaqus/CAE displays its name in the title bar of the main window.
Before you save the current model database for the first time, it exists only in memory and has no name. When you save the current model database for the first time, Abaqus/CAE displays the Save Model Database As dialog box to allow you to enter a name; subsequent saves use this name and append changes made during the current session to the previously saved model database. If you omit the file extension, Abaqus/CAE appends .cae to the file name.
For information on saving the model database to a new file using a different name, see “Saving the current model database to a new file with a different name,” Section 9.7.11. For more information on saving files, see “Using file selection dialog boxes,” Section 3.2.10.
You should save the model database periodically. Abaqus/CAE never saves the model database unless you perform an explicit save operation; there is no timer-based automatic saving, for example. If you try to save a model database that has not been modified, no action is taken.
Abaqus/CAE asks you if you want to save a modified model database before you exit the session.
The FileSave command does not compress the model database even if you have deleted items from the model. To reduce the file size when you have deleted model contents, use the FileCompress MDB command or save the model database to a new file name (using the FileSave As command).
