How do you handle the singularity in polar or cylindrical coordinates?
Let me show this specifically for the finite element discretization of the Laplace equation:
$$
-\frac{1}{r} \frac{\partial}{\partial r} \left(r \frac{\partial}{\partial r} u(r,\theta)\right)
- \...

finding discretization error in Burger equation
I believe what they do here is much simpler than what you are thinking. The backward Euler discretization error is not computed from a theoretical consideration but simply by comparing its output ...
