HEATED_PLATE
  FORTRAN90 version
  A program to solve for the steady state temperature distribution
  over a rectangular plate.
 
  Spatial grid of      100 by      500 points.
 
  The iteration will repeat until the change is <=   0.100000E-01
 
  The steady state solution will be written to "sol_100x500.txt".
