When you save a model database (by selecting FileSave or FileSave As from the main menu bar), ABAQUS/CAE also saves a model database journal file (model_database_name.jnl) containing the ABAQUS Scripting Interface commands that will recreate the model database. Should the saved model database become corrupted, you can recreate it by starting ABAQUS/CAE with the recover option. (Type abaqus cae recover=model_database_name.jnl.) The recover option executes the commands in the specified model database journal file.

The model database journal file differs from the replay file in that it does not contain every operation performed during a session. The model database journal file contains only the commands that change the saved model database; for example, commands that create or edit a part, change the time incrementation of an analysis step, or modify the mesh. Operations that do not change the model database are not saved in the journal file; for example, sending an image to a printer, creating a viewport, rotating the model, or viewing results in the Visualization module.

As you continue to work on your model, the model database in memory will differ from the most recently saved model database. The model database journal file is updated only when you perform an explicit save of the model database using FileSave or FileSave As. If you copy the model database to a different location, you should also copy the associated model database journal file. Otherwise, you will not be able to recreate the model database.
