A unipolar injection is established between an inner cylindrical
core and an outer grounded cylinder by means of a voltage
difference. The gap between cylinders is filled with a dielectric
medium. A front of charge traverses the dielectric medium and finally
the steady solution shown in figure 199 is reached. The
simulation uses a polar coordinate metric.
