Values displayed on the status bar

The status bar, located at the bottom of the application, provides a quick reference to the state of your project and key settings. It keeps you informed about important configuration details and the current status of your simulation at a glance.

Here’s what you’ll find in the status bar:

• Auto-Lengths: On/Off – If enabled, pipe lengths are automatically calculated based on their drawn position. If disabled, you’ll need to manually enter lengths for each pipe.
• Auto-Elevations: On/Off – When turned on, elevations are assigned automatically using global elevation data. If off, you must input elevation values manually.
• Units: Displays the active unit system, such as LPS (liters per second) or GPM (gallons per minute), ensuring consistency in calculations and reporting.
• Headloss Equation: Indicates which formula is used for hydraulic calculations
  • HW - Hazen-Williams
  • C-M - Chezy-Manning
  • D-W - Darcy-Weisbach
• Demand Multiplier: The current multiplier that is applied to all base demands on junctions
• Simulation Status: Provides real-time feedback on the state of the simulation (see below for detailed information on each possible status)

Simulation status

Ready to Run

• Meaning: A simulation has not yet been run for the current network configuration (e.g., you just opened the project or created a new one). No simulation results data is available.
• Action: Click the Simulate button (or use the shortcut Shift+Enter / ⇧Enter) to perform the hydraulic calculations.

Run Successfully

• Meaning: The hydraulic simulation completed without any detected errors or critical warnings. The results shown (e.g., pressures, flows in the Assets Tab and Analysis Tab) are up-to-date and reflect the current network setup.
• Action: You can now analyze your simulation results.

Simulation with Warnings

• Meaning: The simulation completed successfully, and results are available. However, the EPANET engine generated one or more warnings during the calculation. These warnings might indicate potential minor issues, inaccuracies, or unusual hydraulic conditions that you should review.
• Action: Click the Report button (or use the shortcut Alt+R / ⌥R). Review the specific warnings listed to understand their potential impact and determine if any model adjustments are necessary.

Simulation Outdated

• Meaning: You have made changes to your network model (e.g., modified pipe properties, adjusted demands, moved nodes) since the last time a simulation was successfully run. The results currently displayed are from that previous simulation run and may no longer accurately represent the behavior of your modified network.
• Action: Click the Simulate button (or use Shift+Enter / ⇧Enter) again to rerun the simulation and update the results based on your latest changes.
