Description :-

Objective of the program is to solve for the steady state voltage distribution in a region x from 0 to 30 units, y from 0 to 30 units, given that one of the sides of square is excited with a voltage of 45*(x/xmax)*((xmax-x)/xmax) Volts (xmax=30) and all other sides are maintained at 0 Volts. This voltage at the boundary is symmetrical with its maximum value at centre of the boundary namely at x=15.
