It looks like NDSolve is designed to only work with initial value problems. There's a note in the documentation under NDSolve / Possible Issues/ Partial Differential Equations that doesn't work with Laplace's equation, and in the tutorial/NDSolveOverview you can read more about the methods NDSolve uses; none of them are for elliptic equations. One way you could try to work around this is to add a time variable to your problem, specify some initial condition, and see if the solution relaxes to a steady state. This is kind of clumsy, but it might be worth a shot. -Daniel
