During June 2025, Katrin Schoenlein contributed to the DLR-AMR/t8code repository by focusing on improving documentation accuracy and maintainability. She identified and corrected a typo in the documentation for the t8_dtet_type_face_to_boundary array, clarifying its relationship to parent element boundary computations. This targeted fix, implemented in C, enhanced the clarity of the codebase and reduced the risk of future misinterpretation by other developers. Katrin’s work emphasized code review and documentation skills, ensuring that technical details were precisely communicated. While no new features were added, her contribution strengthened the project’s maintainability and supported ongoing collaborative development within the team.
