Backing up a run creates a backup file of the results at the end of the timestep that is currently calculating. This file contains sufficient information for restarting a run for visualization. If a solution may be diverging and an intermediate solution must be retained, you should generate backup files.
To back up a run, either:
Select Workspace > Backup Run.
Click Backup Run
.
The backup file is stored in a subdirectory within the working directory. This subdirectory is given the same name as the current run.
