Hartland contributed to the LLNL/serac repository by developing and refining advanced solver workflows and build system configurations over four months. He implemented quadratic program testing scaffolding and integrated the STRUMPACK backend to enhance sparse linear algebra support, using C++ and CMake to standardize test builds and automate validation. Hartland expanded inertia relief capabilities with a Homotopy solver, improved code quality through refactoring and formatting, and introduced a flexible linear solver API to decouple solver selection. His work included CI-ready build scripts, expanded test coverage, and cross-platform compatibility toggles, resulting in more reliable, maintainable, and extensible software for solid mechanics applications.

May 1, 2025May 2025 performance summary for LLNL/serac: Delivered inertia relief workflow with Homotopy solver, including a new inertia relief scaffold, refactor of InertialReliefProblem, Paraview visualization, and inertia_relief example files. Implemented a flexible linear solver API that decouples solver choice from solvers, adds explicit solver-setting API for HomotopySolver and ParInteriorPointSolver, and ensures a safe default when no solver is configured. Fixed a critical reliability issue by adding a runtime check in IPNewtonSolve to verify a linear solver is configured, preventing undefined behavior. Improved code quality by removing legacy print statements and tightening API boundaries. These changes expand advanced structural analysis capabilities, improve reliability and interoperability, and reduce user error, delivering tangible business value.
