The overset grid consists of a central grid and multiple dense, atom-centered subgrids that allow the simultaneous spherical expansions of the wave function about multiple centers. Scattering boundary conditions are enforced by using a basis formed by the repeated application of the free particle Green's function and potential, $\\hat{G}^+_0\\hat{V}$ on the overset grid in a \"Born-Arnoldi\" solution of the working equations.
