+// This example shows how to implement a circuit with discrete elements in a
+// finite element simulation. Only lumped resistors, voltage- and
+// current-sources are used. There are four separate cubes, each with a certain
+// conductivity. The bottom of all cubes is kept at a constant voltage via the
+// constraint Voltage_3D. The top of the cubes are connected with a circuit
+// according the `R_circuit.jpg' schematic.
