Can I simulate a geothermal field with double-u boreholes in OpenStudio, without use of GLHEPro? I alredy know the proprieties of the ground and the borehole (tube and grout) and also the g-function of the field.
If I put this values in OS:GroundHeatExchanger:Vertical and I run the simulation, it give me this error: Severe ** Plant temperatures are getting far too cold, check controls and relative loads and capacities
