Apr 1, 2025April 2025 monthly summary for pyro-kinetics/pyrokinetics focused on data integrity, numerical robustness, and testing readiness in core simulations. Delivered concise fixes that reduce edge-case failures and improve stability of kinetic calculations, while keeping a clean, auditable commit history. Impact highlights: - Ky Value Positivity Enforcement: Ensured ky is always positive by applying absolute value in cgyro calculations; two commits addressing the same bug (8a371b087b3b6421833325e0935423dd0e76f290 and bba753e045f15e524c61bd9ec8678f6f07f6366d) to stabilize sign conventions and prevent downstream errors. - Robust Species Charge Rounding: Replaced np.isclose with np.allclose to verify that all elements of the species charge array are near integers before rounding, improving robustness of the psi_n grid construction (commit 334edb0c61d299258661be4bd4555f3eee1af9b3). - No-op Placeholder Commit for Testing: Added a placeholder commit for testing purposes with no functional changes (commit cf666f1fbf34376aac1668698452b59eb6bdbfe8). Technologies/skills demonstrated: - Python and NumPy for numerical correctness (abs-based sign handling, allclose-based rounding checks). - Incremental refactoring and commit hygiene to solidify traceability. - Testing-friendly workflow with placeholder commits to validate CI pipelines. Overall impact: More reliable simulations, fewer numerical edge-case failures, and stronger assurance of downstream results for kinetic analyses.
