Focused on MFEM-MOOSE ecosystem improvements with concrete, auditable commits across docs, FESpace basis handling, low-order solver validation, build tooling, and test data maintenance. Business value centers on faster onboarding, more robust simulations, and streamlined CI.

May 2025 focused on expanding LOR capabilities, improving verification, and strengthening code quality for Moose. Key outcomes include broadening LOR coverage to all solvers (diffusion, transient, Hypre, and SuperLU) with supporting tests; refactoring LOR solvers into a common base class with parameter propagation; expanding unit tests and solver verifications; extensive linting and code-quality improvements; and several stability and documentation updates that improve reliability and developer productivity, enabling more accurate and scalable simulations for customers.

April 2025 monthly summary: Key stability improvements and foundational solver enhancements across two repositories. In aurora-multiphysics/platypus, the build risk was mitigated by rolling back the MOOSE checkout to a known-good commit to avoid a capabilities module bug, ensuring consistent builds and production readiness. In idaholab/moose, introduced the Low-Order Refined (LOR) solver groundwork for MFEMCGSolver and refactored the solver infrastructure to support LOR updates, including integration into MFEMProblem and updates to MFEMProblemData to use shared_ptrs for the solver and preconditioner with streamlined updateSolver methods. These changes improve robustness, maintainability, and future extensibility, enabling more reliable experimentation and performance-oriented development across the stack.
