NWChem is a computational chemistry package that can be used to perform electronic structure calculations on molecular and periodic systems as well as classical molecular dynamics simulations. It is designed to run on high-performance parallel supercomputers as well as conventional workstation clusters. The aim of the program is to provide scalable solutions for large scale atomistic simulations. It has been ported to almost all high-performance computing platforms, workstations, PCs running LINUX, as well as clusters of desktop platforms or workgroup servers.

The package includes a range of capabilites including: Hartree Fock, Density Functional Theory (including most of the state-of-the-art exchange-correlation functionals), Higher order many body approaches like Coupled Cluster Theory and MP2, Relativistic approaches like Douglas-Kroll-Hess (DKH) and ZORA, Planewave based Car-Parrinello Molecular Dynamics (CPMD), Excited-State approaches using CIS, TDHF, TDDFT, EOMCC Theories, Classical Molecular Dynamics, Geometry Optimization (minimization, transition state), Vibrational frequencies, ONIOM, COSMO solvation model and various properties. The package also features a QM/MM module that allows one to combine most of the above approaches in a seamless manner.

NWChem is developed and maintained by the Environmental Molecular Sciences Laboratory (EMSL) located at the Pacific Northwest National Laboratory (PNNL) in Washington State. The latest release (version 6.0) of the code is distributed under the terms of the Educational Community License (ECL) version 2.0.
