This example validates the implementation of IBPSA.Fluid.Geothermal.Borefields.BaseClasses.Boreholes.BaseClasses.Functions.multipoleThermalResistances for the evaluation of the borehole thermal resistances.
The multipole method is used to evaluate thermal resistances for a double U-tube borehole with symmetrically positionned pipes. Results are compared to reference values given in Claesson (2012).
