Dec 1, 2025OpenFUSIONToolkit/JPEC — December 2025: Focused on kernel reliability, testing infrastructure, and modularization across VACUUM and EQUIL components. Delivered Kernel Functionality Enhancements with periodic interpolation and integrated tests, fixed kernel residue term, and expanded test scaffolding and datasets to improve CI coverage. Modernized Wall data structures and spline APIs (migrating to CubicSplines/BicubicSplines) to reduce duplication and simplify maintenance. Implemented performance and stability improvements, including a ~10% speedup in initialize_plasma_surface, elliptic integral accuracy improvements, and guards against division by zero. Also completed notebook compatibility and data-type updates to align with new test structures.

Oct 1, 2025Month: 2025-10 — OpenFUSIONToolkit/JPEC delivered a focused feature enhancement with a clean commits approach. Key feature delivered: Vacuum Wall Simulation Enhancement, introducing the wwall subroutine in Vacuum_wall.jl to improve wall interaction fidelity and performance. Major bugs fixed: none reported this month. Overall impact and accomplishments: higher-fidelity vacuum simulations enable more accurate physics modeling and faster iteration for validation and development. Technologies/skills demonstrated: Julia development, module integration, performance-oriented coding, and disciplined version-control practices as evidenced by a targeted commit (6a707e4ce13a7ac1aa4d79fb139acbaae04b139e).

Aug 1, 2025Month 2025-08 — OpenFUSIONToolkit/JPEC: This month focused on establishing robust development infrastructure, validating core numerical results, and improving performance potential of the vacuum simulation. Key outcomes include the creation of documentation and testing workflows, repository hygiene improvements (.gitignore and Project.toml), verification of the green function against original Fortran code, and a kernel refactor to boost execution counts and enhance output handling. These efforts reduce onboarding time, increase reliability, and position the project for stronger CI automation and faster iteration.
