### Nonlinear differential equation: numerical solution

Introduction I think there are several questions on this site about ODEs of the form $$(x-a)^2 u''(x) = F(x,u,u')$$ with an initial condition at $x=a$. There is no general guarantee that solutions ...

### Setting Up Boundary Conditions for Magnetostatic PDE

Well, I'm not quite familiar with electromagnetism and it's not immediately clear to me how to compare the numeric solution with the analytic solution, but I've circumvented the ...
