Hi!
I had some questions when I read pooma tutorials. Now as this mailing list do exist I'll ask one of them.

Laplace's equation in two dimensions is: d²V/dx² + d²V/dy² = 0 where V is, for example, the electric potential in a flat metal sheet.

    How a flat metal(perfect conductor as I suppose) sheet could have a potential distribution? It has only the charge distribution,
but the electric potential is constant on the conducting surface in (quasi)static case.

Cheers,
    Roman.
