The items on the Run toolbar are described below.
Run ButtonClick this button to run the simulation.
Pause ButtonClick this button to pause the simulation. When a simulation is running, the Run button changes to the Pause button. When you click the Pause button, it changes back to the Play button.
Stop ButtonClick this button to stop the simulation while it's running. If you start the simulation again, it'll start at the beginning of the simulation.
Save ButtonClick this button to save the most recent run with a new name (instead of the default Run 1, Run 2, etc.). This button is available in Explore or Experiment mode after a run is made.
Data Manager ButtonClick this button to open the Data Manager. This button is available in Edit mode.
Restore All Devices ButtonClick this button to delete all runs and associated data, except those specifically designated by run name in tables and graphs.
The Progress bar shows the current progress of your simulation. It's also a slider you can use to move to a specific point in the simulation.
This dropdown list will appear at the end of the Run toolbar when you're in Model view and there are messages about equations (which prevent running) or units. To look at the messages, open the dropdown and select a message. You'll be taken to the associated variable on the diagram, and the properties panel will open on its equation.
The Time Indicator shows the progress of the simulation, by showing the current time value.
