Epanet app vs. epanet lib behaviour

Hello,
I’m using the epanet app to compare simulation results with the epanet.lib in python. I’ve noticed that there’s some drift between the two sets of results and, on closer inspection, these occur after a ‘System unbalanced’ report when running the epanet.lib. I take it that the app and the lib handle this situation differently, is that correct?

Best,
Gareth.

Hi Gareth,
how much is this drift? And which variables does it involve? Did you check if there are differences in terms of decimal places precision of the results between app and .lib?
Anyway, try to check if the epanet versions are the same. Are you using DDA or PDA?
