PROFILE
Vera Sidorenko
Vera Sidorenko focused on enhancing the stability and reliability of the FESOM/fesom2 geophysical modeling codebase by addressing two critical bugs related to mesh data handling and metric factor computations. Working primarily in Fortran, she corrected allocation and mapping issues for 2D element nodes and refined the extrapolation logic for 3D nodal data, preventing out-of-bounds errors. Additionally, she resolved array indexing problems in geophysical metric calculations, ensuring accurate assignment and reducing the risk of simulation failures. Her work demonstrated strong debugging and code review skills, resulting in safer mesh processing and more trustworthy numerical modeling outcomes for scientific computing.

Sep 1, 2025Monthly summary for Sep 2025: Core stability and correctness enhancements in FESOM/fesom2. Delivered critical bug fixes addressing mesh data handling and geophysical metric computations. 1) Bug: Mesh data handling correctness (elem2D_nodes and extrap_nod3D) — corrected allocation/mapping and extrapolation loop upper bound to prevent read/extrapolation errors and out-of-bounds access. 2) Bug: Correct metric factor indexing — fixed array indexing for metric_factor so it assigns to the correct element (index n). Result: safer mesh processing, accurate geophysical calculations, reduced risk of simulation crashes or incorrect results. Demonstrated strong debugging discipline, code review, and use of version control. Business impact: improved reliability of the solver, fewer downstream failures, and more trustworthy results for decision-making.
