LAMMPS
Public development project of the LAMMPS MD software package
LAMMPS is a large-scale classical molecular dynamics simulator for modeling atoms, molecules, coarse-grained particles, and other particle-based systems. It is designed for high-performance computing and can run efficiently on desktops, clusters, and supercomputers. The software is widely used in materials science, chemistry, physics, nanotechnology, soft matter, and computational engineering. -

Molecular Dynamics Studio
Molecular Dynamics Cell Construction
...PACKMOL can generate a random collection of molecules using the molecule templates from NanoEngineer-1 thus providing the initial MD cell. Modifications to PACKMOL allow the atom type data to be passed through to the MSI2LMP software. MSI2LMP creates a LAMMPS input file based on class I or class II force fields. MSI2LMP was modified to use numerically coded force field data generated by NanoEngineer-1. The MMP file format was extended and integrated into all three software applications. http://www.nanoengineer-1.net http://www.ime.unicamp.br/~martinez/packmol/ http://lammps.sandia.gov/ -

MUSE
A Multi-algorithm Collaborative Structure-prediction Environment
MUSE is short for Multi-algorithm-collaborative Universal Structure-prediction Environment, which was developed for easy use in structure prediction of materials under ambient or extreme conditions, such as high pressure. It was written in Python and organically combined the multi algorithms including the evolutionary algorithm, the simulated annealing algorithm and the basin hopping algorithm to collaboratively search the global energy minimum of materials with the fixed stoichiometry.... -

These scripts demonstrate the ability of one-dimensional formulations to reproduce the axial strain field of tensile single-walled carbon nanotubes (SWCNTs). The LAMMPS scripts return the molecular mechanics solution for some armchair and zigzag SWCNTs, while the Matlab scripts compute the numerical solution of a one-dimensional integro-differential tensile rod by B-spline finite elements. By using the proper set of nonlocal parameters, it is possible to correctly capture size and chirality effects observed in the axial strain profile computed with molecular mechanics. ...

Jazz, a scientific research tool, is a new python wrapper for LAMMPS implemented to calculate the lifetimes of vibrational normal modes based on forces as calculated for any interatomic potential available in the package. The anharmonic character of the normal modes is calculated via the Monte Carlo-based moments approximation as is described in Yang Gao and Murray Daw, Modeling and Simulation in Materials Science and Engineering (2014).

sphrheo
SPH add-on to LAMMPS for the rheology of Non-Newtonian liquids
This package comprises a set of add-ons to the popular LAMMPS molecular dynamics software to study the rheology of Non-Newtonian liquids with moving boundaries. Licensed under the GPL, this software is free to use and reproduce under the same terms. It is simple to install and extend. At the current stage, it provides libraries for strain-rate dependent viscosity, a dynamic stress model (Rolie-Poly), and the inclusion of colloidal particles in a viscoelastic solvent. -

createSimulationBoxForLammps
create complex simulation box for lammps
Creating a complex model for Lammps is a headache for someone like me! A python written script, createSimulationBox.py, is created to make the pre-processing easier. If you are familiar with Lammps well, it will be so handy; if you are newbie, don't worry, because it only has 6 commands. Moreover, the models(element, molecules like water) are coded in the program, and you are free to contribute your model into this simulationBox creator! -
