A Caution message in AFT Fathom is of less importance than a full Warning. While some Caution messages may be left unresolved without affecting model results, they should never be ignored by the user.

CAUTIONS

• Check Valve closed at Junction X

• Default control valve actions at Junction X used when setpoint not achievable because analysis is transient

• Flow is negative through Junction X. Loss factors may be in error

• Flow solution for Junction X is above/below the maximum/minimum value specified for the resistance curve. Flow rate: Y

• Head loss, head rise, hydraulic gradeline and energy gradeline output does not have meaning for zero g systems

• Head rise across fixed flow pumps is referenced to system g level...

• Junction X has a density change across it. If this is due to a moving interface...

• Note: No scenarios have been set in the Multi-Scenario Output display

• Pipe X elevation of Y is below Reservoir Z tank bottom elevation...

• Pipe X length is shorter than the elevation change (between Junction Y and Z)

• Pipe X segment length Y is shorter than the elevation change.

• Pump X has no efficiency curve data. Nominal efficiency was used in viscosity correction calculations

• Pump X has no efficiency curve or nominal efficiency data...

• Pump X properties were outside of the valid range for the viscosity correction calculations. Results may be invalid

• The performance of Pump Junction XX may be affected by the fluid viscosity.

• The System Life specified in Cost Settings is different from the XTS time

• Transient data did not extend to Stop Time at Junction X

• Velocity in pipe X is less than the deposition velocity (Velocity = Y, Vsm = Z)
