PLANT solves a two-dimensional steady diffusion problem with
space-dependent source and boundary conditions.
It can be tested against exact solution fields.
Governing equation:
d(dT/dX)/dX + d(dT/dX)/dX + S(X,Y) = 0
S(X,Y) = 2.sinX.sinY
Boundary conditions:
Y = 0 ; T = 0
Y = 1 ; T = sin1.sinX
X = 0 ; T = 0
X = 1 ; T = sin1.sinY
Exact solution:
T(X,Y) = sinX.sinY
