Hi,

for the most PDE's there exist no or an infinite number
of solutions without boundary conditions -- a computer
program will need infinite time and memory to find
you solutions.

But in the most cases Mathematica (and no other system)
is even not able to find
a numerical solution of a system of PDE's.

Regards
  Jens
