    Zero-dimensional diffusion problem which can be tested  against
    exact solution.
  =================================================
     dPHI/dt=-PHI^m*t^n, PHI=1 for t=0.
     where
     m=1, 0.<=t<=2.5
     n=0, 0.<=t<=2.5
     m=4,     t> 2.5
     n=3,     t> 2.5
   ================================================
  One computational cell is used in this study of the
  time variation of pollutant concentration.
