Examples of uses for the Poisson Eqn in 1d

[Carla1985]

Hi all,

I have almost finished my dissertation on using the finite element method to solve the 1D version of the Poisson equation. For the last section I would like to run through a couple of examples but am struggling to find some. Obviously I can make up any equations that satisfy the equation, this is what most of the exercises in the books are, but ideally I would like to use some that have real world value. Could anyone either suggest some examples or point me in the direction of some please.

Thanks
Carla

Well, I don't know if you can shoe-horn such a problem into one dimension, but you use Poisson's equation to find the potential due to source charges in electricity and magnetism, and you can also use the exact same math to find the gravitational potential energy field due to an arrangement of masses. So it's of great importance!
