Comments 
 Where are the source and sink ports defined?
Capacitance values can be extracted without assigning source and sink ports. It is only necessary
to specify the conductor nets.
 What results can be obtained from post processing?
Post processing output helps to understand the physical phenomena, by displaying the
distribution of the charge (ABS Q, Smooth Q).
