Monthly performance summary for 2025-10 focusing on delivering core BATSRUS enhancements that improve configuration correctness, test coverage, and reproducibility, with clear business value in reliable simulations and streamlined validation.

September 2025: Delivered enhanced TPSAVE configurability for GMPC FLEKS 2D periodic test file in SWMF, introducing two distinct configurations and new parameters to control species, units, save intervals, and launch thresholds. This enables more flexible, reproducible particle-tracking experiments and reduces setup time for test campaigns.

Monthly work summary for 2025-08 (SWMF). Focused on delivering and stabilizing GMPC FLEKS 2D periodic test configuration for test16_2d in SWMFsoftware/SWMF. Implemented 2D region corrections, adjusted configuration files, and cleaned up temporary validation work to align with Config.pl. Result: more reliable 2D test execution and CI stability, with improved maintainability.

In January 2025, completed a targeted bug fix in the SWMF repository that improves the reliability of FLEKS test particle validation. The update changes the test particle configuration region from 'uniform' to 'tpsphere' and updates test logs to reflect new particle data, aligning test expectations with the actual simulation behavior. The work enhances test accuracy, traceability, and overall confidence in particle-tracking validation, supporting upcoming features and integration efforts.
