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.

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).

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!

Provide a simple way of creating models for molecular dynamics simulation. Especially for LAMMPS.

PyKMC is a work in progress on-the-fly kinetic Monte Carlo package. It currently allows for automatic defect-decomposition, lattice minimisation, NEB and String saddle point calculations and RAT transition searches - using LAMMPS or LBOMD.

Create nanocrystalline samples for molecular dynamics simulation using lammps, the sample shape and grain shape can be various.
