   PLANT is activated  to  introduce  the  complex  source  and  to
   calculate  the exact solution for output purposes to be compared
   against  numerical  one.  Two  alternatives  are  used  for  it:
   FIXVALing  of SOLVEd variable EXCT and re-calculation at the end
   of solution procedure.  The latter is performed in Group 21.
  ===================================================
     Convection-diffusion problem:
        dF/dx=1/Pe*d(dF/dx)/dx+S, where
        S= 1-2/Pe+2x+pi*cos(pi*x)+pi^2*sin(pi*x)/Pe
     Boundary conditions:
        x=0, F=1+exp(-Pe)
        x=1, F=4
     Exact solution:
        F=1+x+x^2+exp(-Pe(1-x))+sin(pi*x)
