A Warning message in AFT xStream

Full Message text is:

The maximum transient pipe temperature (X) was significantly lower than the estimate (Y). The estimated maximum pipe temperature should be set marginally above the maximum.

 

This warning indicates the maximum pipe temperature during the transient simulation is significantly lower than the Estimated Maximum Pipe Temperature During Transient value specified by the user in the Sectioning panel. The estimated maximum temperature is used to help determine the time step for the simulation. In this situation, it's possible that more time steps are used than are necessary to capture the system's transient behavior. Lowering the estimate will make each time step longer, reducing run time.

The user should provide a more accurate estimated maximum pipe temperature and re-run the simulation.
