Gaussian software density code#

LAMMPS is distributed as an open source code under the terms of the GPL. The code is designed to be easy to modify or extend with new functionality. LAMMPS runs on single processors or in parallel using message-passing techniques and a spatial-decomposition of the simulation domain. It can be used to model atoms or, more generically, as a parallel particle simulator at the atomic, meso, or continuum scale. LAMMPS has potentials for soft materials (biomolecules, polymers) and solid-state materials (metals, semiconductors) and coarse-grained or mesoscopic systems. LAMMPS is a classical molecular dynamics code, and an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator. Alternatively, you may add 'module load gaussian' to the start of your existing qsub script. To run, copy the script '/software/Gaussian/Gaussian09/g09_qsub_script' to your work directory, modify it accordingly, then do 'qsub g09_qsub_script'. Upon request, users will be added to an approved user list for G09 access on the CFN cluster.

The latest version available at CFN is G09, revision D.01.Ī valid Gaussian license must be held by the user through his/her home institution. Gaussian is an electronic structure program that predicts the energies, molecular structures, vibrational frequencies and molecular proteries of molecules and reactions in a wide variety of chemical environment. DMol3 can also be used to search very efficiently for transition states using a combination of LST/QST algorithms with conjugate gradient refinement, thereby avoiding the computationally expensive calculation of the Hessian matrix. Owing to its unique approach to electrostatics, DMol3 has long been one of the fastest methods for molecular DFT calculations and can quickly perform structure optimizations of molecular systems using delocalized internal coordinates. CASTEP employs the density functional theory plane-wave pseudopotential method, which allows you to perform first-principles quantum mechanics calculations that explore the properties of crystals and surfaces in materials such as semiconductors, ceramics, metals, minerals, and zeolites.ĭMol3 is a unique density functional theory (DFT) quantum mechanical code that allows users to study problems in the gas phase, solvent, surface, and solid environments. CASTEP is a state-of-the-art quantum mechanics-based program designed specifically for solid-state materials science.
