A Caution message in AFT xStream 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

• All transient junction behavior was disabled

• Assigned Flow at Junction X has a constant flow rate during the transient...

• Automatic Sectioning is enabled, but flow increases substantially during the transient

• Check Valve closed at Junction X

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

• Junction X exceeded maximum event messages

• Junction X is downstream of a choking point, stagnation/static properties cannot be calculated

• Maximum transient pipe Mach number lower than estimate

• Maximum transient pipe Mach number at least 0.2 higher than steady...

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

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

• Transient temperature was within 10 deg. F of minimum temperature

• Transient temperature was within 10 deg. F of saturation temperature
