Understanding the Difference Between Result Mode and Scenario Mode

In models in which scenarios are not being used, there are three modes that the model can be in: Edit Mode, Run Mode, and Result Mode. The model is in Edit Mode while it is being edited, the model is in Run Mode while the simulation is actually running, and the model is placed in Result Mode after results have been generated.

When using scenarios in GoldSim, a fourth mode is introduced: Scenario Mode. Scenario Mode is a special model state that allows scenario results to be displayed and compared. Scenario results can only be compared when the model is in Scenario Mode.

Although Scenario Mode is similar in some respects to Result Mode (in that both modes are used to view results), there are several key differences:

• When in Scenario Mode, scenario results can only be viewed in Time History Result elements, Distribution Result elements and Final Value Result elements. No other results are available. Hence, if your model does not contain any Time History, Distribution or Final Value Result elements, you will not be able to compare scenario results.

• When viewing results in Scenario Mode in Final Value or Distribution Result elements, you cannot view results at Capture Times. Only the Final Result can be viewed.

• A model in Scenario Mode has at least one scenario with results. However, when in Scenario Mode, not all scenarios necessarily have results (since the scenarios can be run independently).

• Models cannot be edited in Result Mode. However, in Scenario Mode, you can edit Scenario Data elements for scenarios that do not have scenario results (i.e., if the Active Scenario does not have results, Scenario Data for that scenario can be edited).

Note: Although you can edit Scenario Data elements for an Active Scenario that does not have results while in Scenario Mode, you can never edit non-Data elements in Scenario Mode, since these are common to all scenarios, and doing so would invalidate scenario results that existed for other scenarios.
