Snapshots

About snapshots

A snapshot is an archive of the state of the simulation at a previous solution. It contains all variable and real parameter values and the variables' specification status. It can also include history data from Dynamics runs. AVEVA Process Simulation allows you to create snapshots so that you can return your simulation to a previous solution. For example, if you are planning to modify a simulation by adding new equipment models or equations, saving a snapshot of your simulation will help you to return to a previous solution.

You can create a new snapshot or return to a previous one from the Application Ribbon or through the Snapshot Manager. You can use the Snapshot Manager to add a description to a snapshot, rename a snapshot, delete a snapshot and more. When you create a snapshot, it is saved with the simulation.

Concepts

• You can create multiple snapshots and return to a specific one

• You can create a snapshot from the Application Ribbon or manage a snapshot in the Snapshot Manager

• When you switch between simulation modes, a snapshot is automatically taken

• All variable and real parameter data is saved with each snapshot

• History data is not saved by default, but you can include history data when you capture a snapshot from the Snapshot Manager

• When you restore a snapshot, you determine what data to load by selecting Reset, Revert, Invariant, or Special

• Snapshot information is saved with the simulation.

• The Snapshots group on the Process, Fluid Flow, and Dynamics tab displays the snapshot that you last loaded.

Actions

• Create, rename, and delete a snapshot.

• Create, rename, and delete a snapshot that includes history data.

• Return to a specific snapshot that you captured.

• Compare a snapshot to the current simulation.
