Myna

Myna is an open-source tool for connecting simulation pipelines with additive manufacturing process data.

Myna was originally developed for the data structure maintained by ORNL MDF’s Peregrine tool for laser powderbed fusion, but has since implemented several other datastructures for integration with other data sources.

The source code and installation instructions can be found on the Myna GitHub repository: https://github.com/ORNL-MDF/Myna

Citing

If you use Myna in your work, please cite the version of Myna used via the Zenodo DOI (link to most recent release). In addition, please cite any of the relevant journal articles:

• Knapp et al. (2025) describes the background for Myna and the 3DThesis, AdditiveFOAM, and ExaCA applications for melt pool and microstructure simulations.
• Knapp et al. (2023) introduces the concept of leverging the digital thread for simulations using the precursor to Myna and provides details on the solidification data clustering approach.

The examples/Peregrine directory used for examples are from the publicly available Peregrine v2023-10 dataset. If you use this data, please cite Scime et al. (2023).
