Return the simulation to the initial point after a Case Study run

During a Case Study run, the software re-solves the simulation for each case. At the end of the Case Study run, the simulation remains at the values from the last case in the Case Study.

Important: Because the simulation retains the values from the last case in a Case Study, we highly recommend that you capture a snapshot of your simulation before you run any Case Studies.

If you choose to manipulate an invariant parameter or variable in the Case Study, the current state of the simulation won't match the configuration in any snapshots that you captured before the Case Study run because a regular snapshot revert does not include invariant values. In this situation, you can perform a special snapshot revert to include the invariant parameters and variables.

If you do not have a snapshot that you can fall back on, you can still return the simulation to the initial point by discarding all simulation changes for the current simulation session. This may result in lost data if you made changes to the simulation or Case Study in the current session, so we recommend that you use this option only if absolutely necessary.

Return the simulation to the initial point by using an existing snapshot

1. Open the Snapshot Manager.

2. Select the snapshot that you want to revert the simulation to.

3. Select Special.

4. Ensure that the following checkboxes are selected:

   • Variable Specified Values (Revert)

   • Variable Calculated Values (Revert and Reset)

   • Real Parameter Values (Revert)

   • Variable Specification Status (Revert)

   • Invariant Values

   

5. Select Load.

   The simulation reverts to the selected snapshot, including any invariant values.

Return the simulation to the initial point without using a snapshot

6. On the Canvas, right-click the tab for the simulation, and then select Discard Changes.

   Important: Discarding changes undoes all changes made to the simulation since you last opened it. You may lose data if you made any changes to the simulation other than running the Case Study.

7. Reopen the simulation.

   The simulation opens to the initial point before you ran the Case Study. All Case Study results are gone.

8. If you made changes to your simulation other than running the Case Study, repeat them for this simulation session.

9. (Recommended) Capture a snapshot of your simulation.
