The way I computed the solution in the linked answer is the classical one: I just took a reference solution (assuming the code was correct, i.e. the numerical solution I found is the right one) with a small enough step size $h$, say $h=10^{-9}$. Then I computed the solution with smaller $h$s and for each one of those $h$ I computed the $|| e_h ||$ in a ...
