We construct a fully-selfconsistent formalism of ab initio electronic-structure calculations, where basis orbitals are localized, nonorthogonal, and given on a real-space regular grid. A window function is adopted to optimize localized basis orbitals. As an example, the ground state of diamond crystal is calculated using the ultrasoft pseudopotential.
