| Research Abstract |
We present a method for performing real-space electronic-structure calculations with finite element method (FEM). The band structure can be calculated with the fast Fourier transformation technique, if necessary. The tetrahedron is used for the element for FEM. We present algorithms for solving the Poisson equation and Kohn-Sham equation with mixed basis and develop the program code for it. In order to generate program code for our method, the object-oriented analysis is applied. As an example, results are present for the calculation of the one-dimensional Kohn-Sham equation for the Hydrogen atom. The advantage of the method is that we can use the Bachelor-Hamann-Schluter type pseudopotential directly.
