As discussed previously, the Output window GSC Variables tab indicates how the input parameters must be varied to satisfy the goals. Once you have these results, you may want to keep and use them in the model. There are two ways to do this: Transferring Results to Initial and generating a Disconnected Scenario.

Transferring Results to Initial

In general, the Output window supports a feature called "Transfer Results to Initial Guesses". This is available on the Edit menu. When used without the GSC module, it transfers calculated results for flow, pressure and temperature to the initial guess values of the pipes and junctions. When used after a GSC run it gives you three options: to transfer the GSC Variable Data only, transfer the calculated results only, or transfer both.

If you choose either of the first two options that transfer GSC Variable Data, the junction data on the Properties window will be changed to the GSC Variable results. This means that one could then choose to Ignore goal seeking, re-run the model, and obtain the same results as before.

Generating a Disconnected Scenario

After a run is complete, a special type of scenario can be created called a disconnected scenario. A disconnected scenario itself breaks the inheritance of normal child scenarios so that it is truly standalone scenario. This is ideal for GSC results in that it may not make sense to save the GSC results for future use if the model can otherwise be changed in arbitrary ways - if the model were changed the GSC results would be invalidated, meaning the user would need to rerun GSC.

For example, assume a GSC run is made to find the valve open position required to achieve a certain flow. If this result is saved, and then the pipe size is later changed, the valve open position would no longer supply the desired flow.

Creating a disconnected scenario helps prevent changes to the scenario since disconnected scenarios cannot be changed by propagated changes from other scenarios.
