Pipe X segment length Y is shorter than the elevation change
A Caution message in AFT Fathom
The pipe has intermediate elevations and the length along one of them is less than the elevation change of that segment. In this situation, pressure loss along the pipe due to friction is calculated using the pipe length the user has defined while static head loss is determined using the elevation change the user has defined. This can be corrected by adjusting the intermediate elevations input.
