PROFILE
Hendriceh
Hendrik Hetmann contributed to the exasim-project/NeoFOAM repository by developing and refining core simulation features for computational fluid dynamics. Over five months, he implemented configurable symmetry boundary conditions, unified field reading APIs, and enhanced time integration reliability, using C++ and CMake with a focus on algorithm design and numerical methods. His work included refactoring the PDE solver for improved accuracy, expanding test coverage, and introducing detailed solver logging to aid debugging and performance monitoring. These efforts improved code maintainability, simulation robustness, and developer onboarding, demonstrating a deep understanding of software engineering principles and the complexities of fluid dynamics simulation.

Mar 1, 2026March 2026 (2026-03) – NeoFOAM: Implemented momentum equation solver logging to improve debugging and performance monitoring. Key feature: logs capturing initial and final residuals and iteration counts per solve, enabling faster diagnosis and data-driven tuning. Related commit: 4a457a24a9ec005a32b057049d13d0de44f8acfc ('Add momentum equation solver logs for updated solve path'). No major bugs fixed this month. Impact: improved solver observability, reduced MTTR, and a foundation for performance optimizations. Skills demonstrated: instrumentation, logging, version control, and solver performance analytics.

Oct 1, 2025October 2025 (exasim-project/NeoFOAM): Delivered new symmetry boundary condition configurability in the NeoN Reader to support symmetryPlane and symmetry, mapped to a new NeoN symmetry BC. No critical bugs reported this month; the integration with the reader and submodule structure is stable. This work enhances modeling flexibility for symmetric domains, reduces manual configuration, and aligns NeoN submodule tracking to the required branch for stable builds.
