cclib

Compare

  Analyzed 1 day ago

cclib is an open source library, written in Python, for parsing and interpreting the results of computational chemistry packages. The goals of cclib are: * to facilitate the implementation of algorithms that are not specific to a particular computational chemistry package * to provide a ... [More] simple and standard interface to the results of computational chemistry calculations, particularly those results that are useful for algorithms or visualisation * to maximise interoperability with other open source computational chemistry and cheminformatic software libraries [Less]

FreeON

Compare

Claimed by Los Alamos National Lab Analyzed about 3 hours 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]
