During December 2024, Georgios Georgakoudis focused on codebase refinement for the boutproject/BOUT-dev repository, delivering a targeted feature that improved maintainability. He removed redundant BOUT_HOST_DEVICE qualifiers from Field2D and Field3D classes, specifically within operator overloading methods and inline functions. This C++ refactoring effort streamlined the code, making it clearer and easier to maintain while potentially reducing compilation times by eliminating unnecessary annotations. Georgios applied his expertise in C++ and software development to enhance the readability of core data-field implementations, laying a foundation for smoother onboarding and faster future development. No major bugs were addressed during this period.
