A Caution message in AFT xStream

Full Message text is:

Transient temperature was within 10 deg. F of minimum temperature at X seconds.

 

This is a cautionary notice that the temperature at some point in the system approached the minimum temperature for the fluid in the database during the transient simulation. This means that some properties may be extrapolated beyond the range of the available data. In some cases this may also mean that the saturation conditions were reached. The user should review the results to verify that saturation conditions were never reached.
