The test for “3-BHE Array Coupled With Pipe Network” (i.e. 3bhes_1U.prj) has run OK without errors for full simulation of 180 days (15552000 seconds).
Soil temperature range over 180 days is now 9.6 degC (9.637 degC)
Following the advice from @ShuangChen , to subtract 30 degC from the results:
temperature soil [306.209, 315.846] degKelvin
temperature soil [33.059, 42.696] degCelsius
temperature soil [3.059, 12.696] degCelsius adjusted (subtract 30)
temperature BHE1 [0, 299.9], [0, 300.63], [0, 308.314], [0, 308.314]
temperature_BHE2 [0, 299.864], [0, 300.562], [0, 308.071], [0, 308.071]
temperature_BHE3 [0, 299.9], [0, 300.63], [0, 308.314], [0, 308.314]
@ShuangChen – I have attached the results and the amended .prj file if you would like to comment further. The amended .prj file is there for anyone else who wants to run the full simulation, using OpenGeoSys v6.4 on Ubuntu 20.04, described here:
Updating the documentation for “3-BHE Array Coupled With Pipe Network” would be helpful. Especially given the anomaly when using tespy, if the flow temperatures approach zero:
