Pipe X temperature is outside temperature limits in AFT Arrow Steady Solution Control

A Warning message in AFT xStream

Full Message text is:

Pipe X temperature is equal to or greater than the maximum temperature limit (equal to or less than the minimum temperature limit) of Y set by the user in Solution Control. Results may be incorrect.

 

The user has temperature limits defined in the AFT Arrow Steady Solution Control panel. These limits control the search space for temperatures while solving. However, the final solution had one or more pipes at the temperature limit, meaning the limit restricted the solution and may give incorrect results. The user should either remove or change the temperature limit.
