Description :-

Objective of the program is to solve for the steady state voltage distribution in a region, given that one of the sides of square is excited with a voltage and all other sides are maintained at 0 Volts. A steady state charge distribution of RHO exists in domain. At any iteration, the value of voltage is updated as average of voltages of 4 nearest neighbors, until between consecutive iterations, the error is less than 0.01 V.
