SimLAMMPS

SimLAMMPS is a SimPhoNy wrapper that enables the use of the LAMMPS molecular dynamics simulation engine on the SimPhoNy Open Simulation Platform.

Installation

This wrapper requires a working LAMMPS installation. If you are running Ubuntu or CentOS, you are lucky, as we have prepared a script that can install it for you.

    ./install_engine.sh

If you are running a different distribution or operating system, you will have to install it yourself. Please make sure that LAMMPS is installed before proceeding.

The next step is to install the wrapper itself. SimLAMMPS is available on PyPI, so it can be installed using the pip package manager, you can do so by running:

    pip install simphony-osp-simlammps

Finally, the wrapper requires a specific ontology to operate. Download the ontology file and ontology package, then install the latter with the following command:

    pico install simlammps.yml

Note: The provided ontology is not connected to any top-level ontology, therefore its scope is limited to this wrapper.

Docker

Alternatively, you can run the wrapper from a Docker image. We have prepared a Dockerfile with all the necessary requirements.

    # Build it
    docker build -t simphony/simlammps .
    # Run it (console entrypoint)
    docker run -ti --rm --entrypoint=/bin/bash simphony/simlammps
