High-performance computational chemistry software
nwchem input_file
nwchem provides many methods for computing the properties of molecular and periodic systems using standard quantum mechanical descriptions of the electronic wavefunction or density. Its classical molecular dynamics capabilities provide for the simulation of macromolecules and solutions, including the computation of free energies using a variety of force fields. These approaches may be combined to perform mixed quantum-mechanics and molecular-mechanics simulations.
There are no command line options to use.
There is a comprehensive online manual at http://www.nwchem-sw.org/index.php/NWChem_Documentation.
