Critical Warnings, Warnings, and Cautions

A number of warnings may be given in the output when you run an AFT Impulse model. These warnings are intended to alert you about potential problems with the model or solution. There are different warning levels depending on the severity, but all warning types should be reviewed when they are displayed in the output.

CRITICAL WARNING – Very important and reflects a high possibility of incorrect results in the output. Output with critical warnings should be used only for error resolution purposes and never for engineering decisions.
WARNING – Offers important information about the converged solution or the model itself.
CAUTION – A cautionary warning is of less importance than a normal warning or critical warning. The included information may or may not be of interest to the user.
INFORMATION – An Information message is only intended to make the user aware of an advanced feature being used in the model. This advanced feature could cause incorrect results if not applied properly. If the user understands the feature then no action is required.

Any of the warning message types above can be double-clicked in the Output window to take you directly to the pipe/junction referenced in the message. Whenever any warnings occur that are of the WARNING or CRITICAL WARNING level, the General Results section of the Output Window will be displayed with the text in red.

The above links will take you to a list that includes most of the warnings you may receive, with a brief explanation given for each.
