Recommended steps

1. Create or load a project: Files → “Load JSON” or “Import EPANET .inp”; or start blank.
2. Review the network: use zoom/pan and the floating table to list nodes/pipes and spot missing data.
3. (Optional) Georeferenced background: in Settings add an image or MapTiler basemap and calibrate scale if needed.
4. Configure simulation: in Analysis, choose method (GGA/N-R/EPANET) and, if needed, adjust tolerances or preset.
5. Run the calculation: click the chosen button; check the status banner and timing.
6. View the color map: in View, pick the metric (Pressure for nodes, Velocity/Headloss for pipes) and enable “Flow direction” if needed.
7. Review results: open the floating table, sort by pressure or velocity, and take notes.
8. EPS: in EPS mode, open the EPS Profile panel to inspect time series.

Good practices

• Before calculating, ensure every pipe has diameter/length and demand is set on consuming nodes.
• If convergence fails, try EPANET (Compare) to validate and review units.
• Tweak label modes and offsets to keep the canvas readable.

Mini case: first run

• Import an example .inp.
• Analysis → “Run Calc” (GGA).
• View → Pressure on nodes; look for red zones (low pressure).
• Node table → sort ascending pressure to find critical points.
