1D Schrodinger equation

I want to solve radial Schrodinger equation for Hydrogen atom in comsol. So I use 1D axisymmetric coefficient form PDE and solve for eigenvalues with boundary conditions as u =0for r----> 0 and Infinity. I cannot get the degeneracy of energy states as in 2D H atom example.
I have attached my model here. Could anyone please tell me what am I doing wrong here ?

Hi,buddy! Do u solve this problem now?
Here is attached modified example from the OP's post. One needs to create denser mesh (user defined) and extend Dirichlet boundary condition to larger r for f->0 when r->\infty. When one does it, then it looks like you get properly degenerate eigenvalues as it should be for the hydrogen atom.
Hope that helps.
