Jun 1, 2025June 2025 monthly performance for trixi-framework/Trixi.jl focused on improving attribution, robustness of non-conservative term handling, and expanding validation coverage in the DGSEM solver. Key features delivered include documentation attribution improvements and subcell limiting for non-conservative systems, complemented by new validation examples. Major bug fix addressed Dirichlet boundary conditions for non-conservative equations, with corrected argument order in nonconservative_flux_function and updates to test references. Overall impact includes improved contribution transparency, more reliable non-conservative simulations, and an expanded test/validation suite, contributing to faster onboarding and increased confidence for downstream users.

Apr 1, 2025April 2025 focused on targeted refactoring to improve maintainability and consistency in Trixi.jl, with a clear emphasis on reducing duplication and aligning tests with architecture changes. The month delivered a unified create_cache path across AMR controllers and mesh types, consolidating cache creation logic into a single location and simplifying future enhancements. Tests were updated to reflect the new controller-mesh alignment by switching the 3D p4est test to ControllerThreeLevelCombined, improving test relevance and stability. These changes lay groundwork for faster onboarding, easier maintenance, and more reliable behavior across configurations.
