How can I define an equipotential surface/volume in FEniCS?
I want to solve electrostatic problem for potential. Charge density and medium permittivity are known, so is the potential of a grounded surface. I know how I can implement that.
But I would like to ...

How to write a simple finite element solver in python in order to solve Poisson equation in 2D
I would like to write a simple finite element solver in python in order to solve 2D Poisson equation and then visualize it.
$$
-\nabla^{2} u(x,y)=f(x,y), \quad x,y \quad in \quad \Omega\\
u(x,y) = u_D ...
