If your system loses contact with the license server or your license is otherwise lost during a session, you can save the model database in its current state. Abaqus/CAE displays a message dialog containing the following options:
Try to reacquire a license or check to see if the server is available
Save the model database
Exit Abaqus without saving the model database
Note: If you are in a procedure, such as creating a sketch or editing a material, only the portions of the model completed prior to the start of the procedure can be saved.
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.
