During February 2025, Andrew Salmgren enhanced the AMReX-FHD/FHDeX repository by improving particle visualization output for scientific simulations. He implemented persistent storage of particle data within plotfiles and enabled color-based visualization by scalar field values, using C++ and the AMReX framework. This approach improved the reproducibility and interpretability of post-processing results for particle simulations, addressing the need for more robust data output and analysis. Andrew focused on code cleanliness and maintainability, ensuring that enhancements integrated smoothly with existing parallel computing workflows. The work demonstrated a thoughtful balance between technical depth and practical improvements to simulation data quality and usability.
