Help & user guide

The Builder shows All model changes saved after a successful save. If you edit asset or relationship properties, choose Apply first, then Save. Unsaved model changes means the current canvas differs from the saved model. Edits made while Save is running still need another save. The desktop and mobile navigation menus ask before leaving an unsaved model. Choose Cancel to stay and save, or OK to leave. Supported browsers also warn before refreshing or closing with unsaved edits. Browser Back/Forward and account-menu actions have their own browser/provider behavior, so save before using them. You can also use Model files to download a backup of the applied canvas. Run settings apply to the next simulation and are separate from the saved design. If you edit while Run Model is being submitted, the Builder keeps those newer edits and offers View submitted run for the original submission. Opening that submitted run does not submit another simulation. If a submission reply is lost, keep the same Builder and settings open and check Results before retrying. Selecting an asset or opening its properties does not turn an unchanged retry into a new submission.

Open Results and use Search recent runs or Run status to filter the latest 50 runs. Each entry shows its creation time and full reference. Use Saved link to this run to keep a direct link. For an older result, expand Open a run by reference and enter its full reference from a saved link or run archive. Searching and reloading only read saved runs; they do not submit another simulation.

Open Model Topology, find your model under Saved models and select Open model. Check Run settings again when the Builder opens; they return to their defaults.

In Model Builder, apply any property edits, then open Model files and select Download model backup. To reopen one, choose its JSON file, review it and select Open as new draft after confirming canvas replacement. Select Save to create a new saved model; existing saved models stay available. Results and run settings are separate. Keep backups private if they describe sensitive systems.

A finite value caps finite data loss within each scenario. Hourly operational loss and repair costs can accumulate separately. Recovery does not refill the finite budget, and repair is charged at each recovery. Probabilities apply every five minutes; check their scale and the simulated duration.

The Free personal workspace includes 25 accepted runs per month. Check Settings: Free plan usage for accepted runs, remaining runs and your next reset date. Choose Reload usage to refresh these details. Reopening a model or downloading an existing result does not submit a new run. Choose 1–1,000 replications and 1–365 days, with replications × days at most 3,000. One accepted submission uses one monthly run, even when it contains 100 scenarios.

Check the saved run in Results before submitting again. It may be queued or still executing. Retry loading or downloading the existing result when those options appear.

Mean is the average scenario cost, P50 is the median and P95 is a higher-cost percentile, not a worst-case guarantee. These amounts cover the recorded period and are not automatically annualized. Do not multiply the mean by the number of replications.
