The Snapshot Manager allows you to capture, reset, revert, rename and delete snapshots, provide a description, and choose simulation snapshot-specific settings to load if you choose to return to a previous state. The Snapshot Manager is accessible from each of the Mode tabs.

Button	Purpose
Snap	Capture a snapshot. Includes Real parameter values, variable specifications and variable values.
Snap with History	Capture a snapshot and include the history data. Includes Real parameter values, variable specifications, variable values, and any history data within Trends. When you include the history data in a snapshot, the file size of the simulation increases and may affect performance if your snapshot includes a large number of Trends or a large amount of history data. The History column in the list of snapshots displays the reset icon for each snapshot that contains history data.
Reset	Load only calculated values to the selected snapshot. When you reset a snapshot, all calculated variables are reset to the unsolved state and the simulation is marked as unsolved.
Revert	Load all data in the selected snapshot. When you revert a snapshot, all calculated variables are reset to the unsolved state and the simulation is marked as unsolved.
Invariant	Load only the invariant data in the selected snapshot.
Special	Load or omit specific snapshot values. See Specified snapshot values for more information.
Flush	Flush all the history data for the Trends in the selected snapshot. The History column in the list of snapshots displays the reset icon for each snapshot that contains history data. After you flush the history data, you can use the History column to verify that your snapshot no longer contains history data.
Delete	Delete the selected snapshot.

Purpose

Snap

Capture a snapshot. Includes Real parameter values, variable specifications and variable values.

Snap with History

Capture a snapshot and include the history data. Includes Real parameter values, variable specifications, variable values, and any history data within Trends.

When you include the history data in a snapshot, the file size of the simulation increases and may affect performance if your snapshot includes a large number of Trends or a large amount of history data.

The History column in the list of snapshots displays the reset icon for each snapshot that contains history data.

Reset

Load only calculated values to the selected snapshot.

When you reset a snapshot, all calculated variables are reset to the unsolved state and the simulation is marked as unsolved.

Revert

Load all data in the selected snapshot.

When you revert a snapshot, all calculated variables are reset to the unsolved state and the simulation is marked as unsolved.

Invariant

Load only the invariant data in the selected snapshot.

Special

Load or omit specific snapshot values. See Specified snapshot values for more information.

Flush

Flush all the history data for the Trends in the selected snapshot.

The History column in the list of snapshots displays the reset icon for each snapshot that contains history data. After you flush the history data, you can use the History column to verify that your snapshot no longer contains history data.

Delete

Delete the selected snapshot.

Example: Select snapshot values to load

You can load or omit specific snapshot values when you revert to a snapshot.

Open the Snapshot Manager.
Select a snapshot.
Select Special. A list of options appears. See Specified snapshot values for more information.
Select the checkboxes for the values that you want to load, and then select Load. The list of options disappears and the snapshot loads.
