Recent tools

• Multi-selection table: column filters, asc/desc sorting, summary averages, and CSV export of the current view.
• EPS Profile: time-series chart for pressure/flow/velocity with min/max/delta in EPS mode.

Pressures

• Check the node table and sort by ascending pressure.
• Below-minimum pressure means poor service or intrusion risk.
• If many nodes are low, review sources (pumps/reservoirs) and trunk diameters.

Flows and velocities

• In the pipe table, sort by velocity or loss.
• Very high velocity → high losses and possible surge.
• Very low velocity → oversizing or dead zones.

Friction losses

• Use the pipe metric Headloss; find segments with highest loss per meter.
• Fix by increasing diameter, lowering roughness, or rerouting.

Problem hints

• Local low pressure: closed pipe, tight valve setpoint, or high elevation.
• Negative pressure: not enough energy; review pumps or levels.
• Slow convergence: loosen tolerances or validate with EPANET.

Quick checklist after a run

• Any nodes below threshold?
• Any pipe exceeding recommended velocity?
• Source levels/curves coherent?
• Units consistent with inputs?
