Katrin Schoenlein contributed to the DLR-AMR/t8code repository by focusing on improving documentation accuracy and maintainability. During June 2025, she identified and corrected a documentation typo related to the t8_dtet_type_face_to_boundary array, clarifying its connection 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 centered on code review and documentation, ensuring that technical details were precisely communicated. While no new features were added, her attention to documentation quality contributed to the long-term maintainability of the project.
