Dec 1, 2025December 2025: Key deliverables centered on enabling production-ready participating media radiation in MOOSE. Implemented Participating Media Radiation Modeling and P1 Validation in LinearFV and CHT solvers, extending the P1 model to couple with energy equations. Built and validated an extensive test suite including 1D temperature coupling, coupled conduction-radiation scenarios, and MultiApps coverage. Completed documentation updates and code maintenance to improve usability and reliability (documentation for LinearFVP1TemperatureSourceSink, wall emissivity in analytical solutions, clang-format alignment, cleanup of unused inputs). No explicit bug fixes recorded this month; the emphasis was on feature delivery, test coverage, and maintainability, enhancing business value by enabling accurate radiation heat transfer simulations across production workflows.

Nov 1, 2025November 2025 performance summary for idaholab/moose: Delivered end-to-end P1 radiation modeling integration in the LinearFV heat transfer module, migrating radiation handling from Navier-Stokes to the heat-transfer framework, and introducing Marshak boundary conditions, along with new radiative source/sink kernels. Implemented radiative source terms in the temperature energy equation and established boundary-condition infrastructure (Robin BC base class, with updates to Marian MarshakBC and FunctorRobinBC). Expanded testing and verification with 1D P1 radiation CSV tests, initial testing files, and thorough documentation, supported by verification tooling. Conducted code maintenance and quality improvements, including clang-format alignment, header updates, and removal of redundant Navier-Stokes tests. These efforts close the radiation modeling gap in linear FV heat transfer, enable validated coupled radiation-heat transfer simulations, and enhance maintainability across the module.

Apr 1, 2025In April 2025, delivered generalized buoyancy support in the Navier-Stokes solver of idaholab/moose and reinforced test reliability. Implemented the LinearFVMomentumBuoyancy kernel to compute buoyancy forces with gravity, density, and momentum parameters, integrating the RHS contribution into the momentum equations. Updated the test suite to exercise the new buoyancy treatment and refined the heated cavity scenario with a reference temperature and reduced mesh resolution to speed validation. These changes enhance physical fidelity of buoyancy-driven flows and reduce test cycle times, enabling faster iteration and more robust thermo-fluid simulations.
