New Repository Location

This repository has been migrated from the University of Exeter GitLab to GitHub to facilitate community interaction and support. The latest version, updates, and collaboration now take place on this GitHub repository.

GitLab Repository (Archived): https://git.exeter.ac.uk/hepplestone/artemis

Why the Migration?

It was decided that this project should be migrated to allow for better community support (i.e. allowing community users to raise issues). All information has been ported over where possible.

ARTEMIS is a software package for the generation and modelling of interfaces between materials.

ARTEMIS is both a Fortran and a Python library, with the option of a Fortran executable. The code relies on recent Fortran features, so has no backwards compatibility with Fortran95.

Documentation

NOTE: The ReadtheDocs is still under development. More guides will be added in the coming weeks and months.

Tutorials and documentation will be provided on the docs website. The methodology is detailed in the paper.

Refer to the API Documentation section later in this document to see how to access the API-specific documentation.

The Fortran executable/app currently has the most extensive documentation. This can be found in two forms:

1. The PDF manual
2. The executable help function (--help and --search flags)

Requirements

• Fortran compiler supporting Fortran 2018 standard or later
• fpm or CMake (fpm works only for Fortran installation)

Python-specific installation:

• Python 3.11 or later (might work on earlier, have not tested)
• NumPy.f2py
• f90wrap
• cython
• scikit-build-core
• meson
• make or ninja
• CMake
• ASE

The library bas been developed and tested using the following Fortran compilers:

• gfortran -- gcc 11.4.0
• gfortran -- gcc 13.2.0
• gfortran -- gcc 14.1.0
• gfortran -- gcc 14.2.0

The library is known to not currently work with the intel Fortran compilers.

Installation

The Python library is not yet directly available from PyPi (this will be made available with the first Python library full release). For now, local pip installation is required.

First, use the following commands to download the ARTEMIS repository:

 git clone https://github.com/ExeQuantCode/artemis.git
 cd artemis

Depending on what language will be used in, installation will vary from this point.

Python

For Python, the easiest installation is through pip:

pip install .

Another option is installing it through cmake, which involves:

mkdir build
cd build
cmake ..
make install

Then, the path to the install directory (${HOME}/.local/artemis) needs to be added to the include path. NOTE: this method requires that the user manually installs the ase, numpy and f90wrap modules for Python.

Fortran

For Fortran, either fpm or cmake are required.

fpm

fpm installation is as follows:

fpm build --profile release

This will install both the Fortran library and the Fortran application for ARTEMIS. The library can then be called from other fpm-built Fortran programs through normal means (usually referencing the location of ARTEMIS in the program's own fpm.toml file). The application can be run using

fpm run

cmake

cmake installation is as follows:

mkdir build
cd build
cmake [-DBUILD_PYTHON=Off] ..
make install

The optional filed (dentoted with [...]) can be used to turn off installation of the Python library. This will build the library in the build/ directory. All library files will then be found in:

${HOME}/.local/artemis

Inside this directory, the following files will be generated:

include/artemis.mod
lib/libartemis.a

How-to

Until recently, ARTEMIS has existed solely as a Fortran executable. This version of the code is currently best documented, but this will change in the near future as the Python library is tested more. To get an example input file, run the following command:

artemis -d example.in

This will generate the file example.in, with the structure of the ARTEMIS input file.

To get descriptions of the tags within the input file, run either command:

artemis --help [all|<TAGNAME>]  
artemis --search <STRING>

API documentation

NOTE: API documentation is not yet set up. It is planned to be implemented in an upcoming release to work alongside the ReadtheDocs and Python library.
