Sep 1, 2025September 2025 monthly summary for mfem/mfem focused on advancing electromagnetic trajectory simulation capabilities and code quality. Delivered the Lorentz miniapp for computing charged-particle trajectories under Lorentz forces, including mesh generation for trajectories via MakeTrajectoryMesh and visualization support. Tightened reliability with robust bounding box handling and a switch to +/-infinity() for initial bounds. Updated user-facing documentation (CHANGELOG, Doxygen references) and kept releases clean by adding relevant data files to .gitignore. Performed maintenance cleanups by reformatting example run commands and updating the copyright year.

9 Commits • 2 Features
Feb 1, 2025During February 2025, the mfem/mfem project progressed in code quality, stability, and user-facing clarity. Key delivery included codebase maintenance and cleanup with license header updates, targeted refactoring of Mesh::Make3D argument alignment, and build-system simplifications, alongside removal of dead code and test cleanups. In addition, the display-basis tool was improved by hiding the unsupported Pyramid element type and documenting the limitation. On the numerical side, correctness and reliability were enhanced by fixing negative Jacobians in element orientation checks and aligning Uk space order with Qk space, together with lowering integration rule order. These efforts reduce technical debt, improve reliability, and deliver clearer behavior to users and developers. The work demonstrates proficiency in C++ code maintenance, build systems, numerical methods concepts, and repository hygiene. Business value: reduced maintenance costs, improved reliability, and clearer UX for developers and users.
