Setting Speed Preferences

The Speed tab of the Run Preferences dialog adjusts how fast a simulation runs. Normal speed is the default simulation speed. When you select a speed setting, the Options button is active and you can make additional settings.

For general instructions, see Setting Run Preferences.

The Speed tab of the Run Preferences dialog has these settings:

Run Mode settings — Determine overall simulation speed.
- Normal Speed — The standard simulation option for general model processing.
- Demo Speed — Runs simulations slowly to make it easier to watch values change in spreadsheet cells and charts.
Options settings — Set update rules for the active worksheet in Normal speed and set processing rate in Demo speed (Speed Tab Options Settings).
Chart Windows settings — Set the redraw rate for any charts open during a simulation.
- Redraw Every _ Seconds — Defines the redraw rate in terms of time. The default value is 0.5.
- Suppress Chart Windows (Fastest) — Closes all charts during simulation. Selecting this option overrides the Show Window preferences set for any charts. This option produces the fastest simulations.
Bring Microsoft Excel to the foreground while running simulations (faster for large models) — When selected, Microsoft Excel runs in the foreground and performance improves.
