This work presents calculated structural parameters and energetic properties of Na- and H-mordenites (MORs) using cluster models with more than 400 atoms. These state of the art calculations were performed within the framework of density functional theory, using both the local density approximation and the generalized gradient approximation, employing(More)
In this paper we propose an iterative method for solving the inhomogeneous systems of linear equations associated with density fitting. The proposed method is based on a version of the conjugate gradient method that makes use of automatically built quasi-Newton preconditioners. The paper gives a detailed description of a parallel implementation of the new(More)
