Pipephase vs. GAP
Pipephase vs. GAP
(OP)
Just wondering if any of you guys have used both programs and could possibly provide a compare-and-contrast from the perspective of the poor user. Thanks!

RE: Pipephase vs. GAP
Bottom line is I always start with the same data set. Set up the model. Calibrate it to match all inputs within 5 psig and (in this model I have two off-system delivery points) all off-system volumes to within 5%. Then without adjusting any calibration parameter I load the second dataset and see if it works. There is a 14 inch line between the two compressor stations and in the second scenario the gas is reversed in that line, if the second run reverses the line then the model is acceptable. Very few ever pass. Neither Gap or PipePhase passed. For problems simpler than my test case both do a workmanlike job. I wouldn't recommend one over the other.

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.
The plural of anecdote is not "data"
RE: Pipephase vs. GAP
I've not used GAP before but am fixing to jump in head first and am thus looking for gotchas. I've been using Pipephase for 25+ years, starting with a time share terminal on a mainframe. I figure the two are pretty similar since there's really only one way to skin this cat.
I appreciate your comment on calibration of the model. Thanks for your input and comments. Pete

I've never really stressed Gap in a live environment. It didn't come close when I tried it against my test case so I dropped it.
