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.
