Summary
👤
Senior🎓
Top SchoolMenno Rijswijk is a developer with 13 years of experience translating scientific and research needs into robust software, currently improving geometry modelling for Rhino at Robert McNeel & Associates. He brings deep expertise in scientific programming (C#, C++, Java, Python, Objective-C) and high-performance computing, honed through long-term roles at MARIN where he developed advanced geometry and grid-generation algorithms for CFD. A PhD-trained chemist, Menno uniquely combines molecular modeling and multivariate data analysis with practical software engineering, enabling precise, research-grade computational tools. He is an active open-source contributor — notably enhancing ParaView’s CGNS reader to handle complex NGON/NFACE element types and adding unit tests to ensure correctness. Beyond code, he has hands-on HPC cluster administration and project management experience, making him effective at taking complex numerical workflows from prototype to production.

Contributions summary:Menno contributed to the CGNSReader module, primarily focusing on enhancing support for reading different CGNS file formats, specifically those containing NFACE_n and NGON_n data. They implemented and refined the code to handle these complex data structures within the ParaView environment. The contributions involved modifications to the core CGNS reader code, including additions to support specific CGNS element types. Furthermore, the user wrote unit tests to validate the correctness of the CGNS reader with various input files.
