Validation of InternalResistancesTwoUTube

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

This example tests the implementation of Buildings.Fluid.Geothermal.Borefields.BaseClasses.Boreholes.BaseClasses.InternalResistancesTwoUTube for the dynamic behavior of the filling material in a double U-tube borehole.
