The first LAMMPS Code Clinic event will take place this summer as an online activity between August 8th, 2022 and September 2nd, 2022. During the Code Clinic event, projects will be discussed and coordinated via Zoom meetings and through the LAMMPS workshop Slack.

The goals of the LAMMPS Code Clinic 2022 are to improve and modernize the LAMMPS source code and documentation, to make it more consistent and user friendly, facilitate collaboration and communication between LAMMPS developers and contributors, assist with porting external source code to be compatible with the current LAMMPS sources, and expand and improve the internal testing facilities.

Participants will have the opportunity to improve their skills working with a community software, collaborate with other LAMMPS developers, become more familiar with the LAMMPS source code and its organization and conventions, and provide a service that benefits the entire LAMMPS user and developer community. Participants may work individually or in groups and there are several projects available for a variety of skill levels.

If you have any questions about the event, please contact developer@lammps.org.


The following list contains the projects and tasks for the event with links to more detailed descriptions.

  1. Improve error messages, reduce need for explanations in documentation

  2. Modernize legacy code in LAMMPS to use newer internal APIs

  3. Update external source code and optionally convert to plugins
