2 Commits • 1 Features
Oct 1, 2025October 2025: Focused API refinement in Conservative Advection for idaholab/moose. No major bugs fixed this month. Delivered getUNodal API improvements with const-correctness, changing the signature to return a const reference and using std::size_t for the index to enable safer, read-only access to nodal velocity data in the advection kernel. Added const qualifier to enforce read-only behavior. Impact: reduces mutation risk, improves code safety and maintainability, and lays groundwork for future performance optimizations in the advection path. Technologies demonstrated: C++, const-correctness, API design, modern references, std::size_t usage, code review practices.
