Reginabuehler
Regina Buehler developed and documented advanced solver tutorials for the 4C-multiphysics/4C repository, focusing on preconditioning strategies and fluid-structure interaction workflows. She created end-to-end guides for solid mechanics and FSI, including example input files, mesh configurations, and detailed explanations of Jacobi, Chebyshev, ILU, and AMG preconditioners. Using C++ and Python, Regina improved onboarding by clarifying distinctions between partitioned and monolithic coupling, reorganizing tutorials for better discoverability, and tightening documentation for reproducibility. Her work addressed both technical depth and user experience, enabling users to benchmark solver performance and adopt high-performance computing workflows with greater efficiency and reliability.

Oct 1, 2025Performance review month 2025-10: Focused on delivering a robust FSI tutorial in the 4C repository and tightening documentation to improve onboarding, reproducibility, and overall user experience. Implemented an end-to-end monolithic FSI tutorial workflow (setup, mesh, boundary conditions, solver configurations) with a 4C input file and guidance for direct and iterative solvers. Cleaned up FSI documentation to clarify coupling methods, and reorganized tutorials by 2D/3D partitioned vs monolithic to reduce search friction. Completed a minor fix to README to improve accuracy. All changes are version-controlled and ready for release notes.

Sep 1, 2025Month: 2025-09 — Key value delivered: two new tutorials on preconditioning strategies for solid mechanics and FSI, plus targeted documentation improvements that enhance onboarding and solver performance analysis. Key outcomes: - Preconditioner Tutorial for Solid Mechanics Solvers: new tutorial with explanations, example input files, and mesh configurations; covers Jacobi, Chebyshev, ILU, and AMG to benchmark large linear systems. - Block Preconditioning Tutorial for FSI Solvers: new tutorial focusing on block preconditioning with documentation, configuration files, and test cases for block-iterative (Teko) and fully coupled (MueLu). - Documentation fixes: corrected typos, stray characters, and updated CONTRIBUTING.md link. Impact: - Enables users to compare preconditioners and optimize large-scale solver performance; reduces onboarding time; improves documentation reliability. Technologies/skills demonstrated: - Preconditioning (Jacobi, Chebyshev, ILU, AMG), block preconditioning (Teko, MueLu), solid mechanics and FSI contexts. - Documentation quality, version control discipline, contribution workflow.
