RAtom
solves nonlinear Kohn-Sham equation for the neutral atom.
RAtom solves nonlinear Kohn-Sham equation for the neutral atom. The adaptive algorithm based on finite element method (FEM) is implemented.
Discretization of the differential eigenvalue problem is done by finite element method with Lobatto polynomials as a basis functions. High order Gauss quadratures are applied in order to obtain the total energy of atom with absolut accuracy of 1E-6 hartree.
Disctretization leads to generalized eigenvalue problem, which is solved by procedures from...
