How to define the boundary conditions on a non-rectangular box in NDSolve?

For example, I need to find potential distribution in an electrostatic problem, when I have several finite metal plates (cylinders or whatever) with fixed potentials. I.e., I need to solve the Laplace equation with some boundary conditions defined on the surface of a rectangular box (no problem with that), but additionally some surfaces inside the box have to be defined and the boundary conditions need to be specified there. How can one do that?
