FreeON

Compare

Claimed by Los Alamos National Lab Analyzed 12 months ago

FreeON is an experimental, open source (GPL) suite of programs for linear scaling quantum chemistry. It is highly modular, and has been written from scratch for N-scaling SCF theory in Fortran95 and C. Platform independent I/O is supported with HDF5. FreeON should compile with most modern Linux ... [More] distributions and OS X. FreeON performs Hartree-Fock, pure Density Functional, and hybrid HF/DFT calculations (e.g. B3LYP) in a Cartesian-Gaussian LCAO basis. All algorithms are O(N) or O(N log N) for non-metallic systems. Periodic boundary conditions in 1, 2 and 3 dimensions have been implemented through the Lorentz field (Γ-point), and an internal coordinate geometry optimizer allows full (atom+cell) relaxation using analytic derivatives. Effective core potentials for energies and forces have been [Less]
