Worked on the KratosMultiphysics/Kratos repository to generalize midside node extrapolation across multiple geometry types, focusing on improving the accuracy and maintainability of geometry processing routines. Refactored the AddRowsForMidsideNodes function to support a broader range of element geometries and introduced a global-to-local node index mapping to streamline the computation of extrapolation matrices. This C++ development effort emphasized robust software design and refactoring practices, reducing future maintenance overhead and enabling easier extension to new geometries. The work enhanced code consistency and readability, laying a solid foundation for future improvements in midside node handling within the Kratos codebase.
