PROFILE
Benno Schoenstein
Contributed to the 4C-multiphysics/4C repository by developing and refining features for solid mechanics simulation workflows, focusing on robust C++ implementations and cross-dimensional reliability. Delivered enhancements to the VTU IO subsystem, enabling named PointData arrays and deterministic ID assignment for improved data referencing and reproducibility. Expanded regression testing to cover 2D and 3D scenarios, addressing edge cases such as empty sets and dimension-dependent behaviors. Fixed memory safety issues and floating-point exceptions in plane-stress solvers, ensuring stable outputs for both 2D and 3D simulations. Utilized C++, CMake, and YAML to strengthen data visualization, file I/O, and finite element analysis pipelines.

Jul 1, 2026July 2026 (4C-multiphysics/4C) monthly summary focused on delivering correctness, stability, and test coverage across 2D and 3D simulations. Key features delivered include a 2D plane-strain compatible fix for Solid::MonitorDbc (replacing a hardcoded 3D DIM with dimension-aware reaction DOF iteration) and the Get_area function robustness against varying node dimensions. Major bugs fixed encompass preventing 2D out-of-bounds reads and uninitialized reaction values by aligning per-condition storage with the actual n_dim and adding a 2D plane-strain regression test. Overall impact: enhanced reliability of 2D/3D simulations, reduced risk of FPE, and improved cross-dimensional consistency, enabling more trustworthy engineering analyses and faster issue resolution. Technologies/skills demonstrated: dimension-aware C++ programming, regression testing, memory safety improvements, and cross-dimensional validation.

Mar 1, 2026March 2026 monthly summary focusing on key accomplishments for the 4C project. Delivered a feature in the IO subsystem that enables named PointData arrays in VTU files and NODE_SET_NAME references in 4C input files. The change preserves backward compatibility by assigning IDs to named arrays after the highest numeric point_set ID, improving flexibility for solid mechanics simulations and reducing configuration friction.
