Boundary Conditions:

The perimeter of the grid is set and fixed to the value of 0.

Interior points are initialized to a value of 100.

Iteration updates interior points.

Convergence to 7 decimal places is observed within 44000 iterations.

Code:

FORTRAN code is available.

JPEG:

JPEG format pictures (0.60 MB) are available for select iterations.
 

MPEG:

MPEG format movie (2.40 MB) shows convergence towards the solution as a function of iteration number.
