Load Scenario
Pull an existing scenario into a workflow so you can analyse it, modify it, or use it as a baseline for comparison.
When to use this¶
- You want to re-run an analysis on a scenario you already built, without rebuilding it from raw files
- You're creating a variant of an existing scenario with a new set of assumptions
- You're comparing two scenarios and need to bring the baseline into the same workflow as the optimized version
What you need¶
- A scenario already saved in this project (via Create Scenario or as the output of a previous run)
Parameters¶
| Parameter | Description |
|---|---|
| Scenario | Pick the scenario from the dropdown. The list shows every scenario in the project. |
How it works¶
Load Scenario emits a full scenario data structure, the same shape that Create Scenario produces. Downstream nodes treat it exactly like a freshly assembled scenario.
Connect the output to compatible analysis nodes from the installed package, or to Create Scenario to save a new named copy. Package nodes declare their input requirements and document how to prepare data for their calculations.
Workflow wiring¶
Save a named copy of an existing scenario:

n1["Load Scenario"] --> n2["Create Scenario"]
Export rows from a stored scenario. The package declares the preferred export table; without a preference, the registered tables are flattened in declaration order:

n1["Load Scenario"] --> n2["Save Data"]
Common mistakes¶
- Picking the wrong scenario. The dropdown shows names. A name a run repeats gets a suffix rather than being merged, so
Baseline,Baseline (2)andBaseline (3)sit side by side with only a number between them. Descriptive names in Create Scenario are the only thing that tells them apart here. - Using a raw-table node to change nested scenario data. Choose a compatible node from the installed package; its ports and documentation describe the accepted input.
Next steps¶
- Create Scenario — save scenario data as a named result.
- Save Data — export rows as a Data Source.
- Browse installed analysis nodes for the calculations available in this deployment.
