Feedback & bug reports:

Development builds exist to be tested, and your feedback directly shapes the upcoming 3.16.0 release. If you run into a bug, a regression compared to the current stable version, or anything else that looks wrong, please let us know in one of the following ways:

To help us reproduce and fix a problem quickly, please include the following information:

  • The exact build you are using — the version and commit id shown above, or the output of ovito --version (desktop application) or python -c "import ovito; print(ovito.version_string)" (Python module).
  • Your operating system and version, and for the Python module also the Python version.
  • A step-by-step description of what you did and what happened instead of the expected behavior.
  • Any error messages or console output, and — if possible — a small input data file and/or session state file (.ovito) that reproduces the problem.
  • Screenshots or a short screen recording, if the issue is of a visual nature.

Please note that the public issue tracker is visible to everyone. If you need to share confidential data or a license-related question, use the email address above instead. For general questions about using OVITO, see our contact page.
