I ran the ".dac" file in the postprocessor of FEFLOW Classic. I saved Geothermal budget export to a ".txt" while exporting budget for an interactively selected segment. To my surprise, the results of imbalance saved to the .txt are not the same as when I ran the original simulation or even when I run the .dac file and observe the budget panel. They are completely different. This is kind of baffling. Is there an explanation why this would occur?
