Coulomb interaction

Hi there I’m new to dolfinx and I have been having a lot of fun playing with the demos and learning how to use it.

I was wondering wether or not fenicsx is capable of solving electric field due to point sources. I have a Gaussian bunch with a 1000 electrons each with their own positions and most of the tutorials deal with fields. How would one go about mapping the positions of the point sources onto a mesh grid creating the charge distribution so I can solve the poison equation and hence find the electric field?
