The fastest way to build a new Nutils simulation is to borrow bits and pieces from existing scripts. Aiming to facilitate this practice, the following website provides an overview of concise examples demonstrating different areas of physics and varying computational techniques:
The examples are taken both from the nutils repository and from user contributed repositories, and are tested regularly to confirm validity against different versions of Nutils.
Users are encouraged to contribute (concise versions of) their simulations to this collection of examples. In doing so, they help other users get up to speed, they help the developers by adding to a large body of realistic codes to test Nutils against, and, in doing so, they may even help themselves by preventing future Nutils version from accidentally breaking their code.
Examples are submitted by means of a pull request to the examples repository, which should add a yaml file to the examples/user directory. The file should define the following entries:
- name — Title of the simulation.
- authors — List of author names.
- description — Markdown formatted description of the simulation.
- repository — URL of the Git repository that contains the script.
- commit — Commit hash.
- script — Path of the script.
- images — List of images that are selected as preview.
- tags — List of relevant tags.
Once merged, the script becomes part of the automated testing suite which runs it at regular intervals against the latest Nutils version. The code itself remains hosted on the external git repository. In case new features merit updates to the script, the developers may reach out with concrete suggestions to keep the examples relevant.
