میدان الکتریکی بین سیلندرهای متحدالمرکز – کامسول

This introduction model creates a simple model of the electrostatics problem with two concentric cylinders of infinite length, which is commonly found in textbooks. Since there is an analytical solution to this problem, the model can be used to compare theory with numerical results from the simulation. Two cases are considered here, one with fixed potentials on both cylinders, and the other with a surface charge density on one cylinder and a fixed potential on the other.
