Hi all, simulation results of EnergyPlus's GSHP system such as borehole wall temperatures and borehole outlet fluid temperatures seem problematic because the temperatures mentioned above may have a abrupt changing by more than 20 degrees(even more)just within an hour. In my opinion, the real physical preocesses will always bear a smoth trend while the inlet water temperature has a smoth curve. So have you guys come across such problems? And is any setting leading to it? Thank you all in advance!
