Lammps langevin

LAMMPS is a classical molecular dynamics code with a focus on materials modeling. It's an acronym for Large-scale Atomic/Molecular Massively Parallel Simulator. LAMMPS has potentials for solid-state materials (metals, semiconductors) and soft matter (biomolecules, polymers) and coarse-grained or mesoscopic systems.WebWebLAMMPS-Molecular Dynamics Tutorial · 8-1 Si-Ar-Si heat transfer ...

I have previously used the Langevin thermostat on ions present in an implicit solvent. The damping parameter was straightforward to set, because I was able to connect it to the viscosity of the fluid.The LAMMPS mailing list was hosted since 2005 at SourceForgeand was discontinued on June 30th 2022. In 2021, LAMMPS joined the Materials Science Community Discoursewebsite as a forum for discussions about LAMMPS. See forum details here. the LAMMPS user and developer community.
