During September 2025, Brian Clayton enhanced the lanl/singularity-eos repository by integrating the Simple MACAW Equation of State (EOS) model, implementing core thermodynamic calculations and ensuring seamless framework integration. He applied C++ and numerical methods to derive thermodynamic properties and developed dedicated unit tests to verify correctness and stability. Additionally, Brian addressed robustness issues in the Carnahan-Starling EOS DensityFromPressureTemperature calculation by refining parameter checks, tuning root-finding tolerances, and improving edge-case handling, particularly for zero covolume scenarios. His work expanded EOS coverage, improved reliability of property predictions, and strengthened the regression test suite, supporting more accurate production simulations.

Sep 1, 20252025-09 monthly summary for lanl/singularity-eos. Expanded EOS capabilities and improved robustness. Key outcomes include integrating the Simple MACAW EOS model into the library, with core EOS calculations, thermodynamic property derivations, framework integration, and dedicated unit tests to verify correctness and stability. Fixed critical Carnahan-Starling EOS DensityFromPressureTemperature issues by refining parameter checks, tuning root-finding tolerances/bounds for numerical stability, and improving edge-case handling (e.g., zero covolume); updated tests accompany the fix. Overall impact: broader EOS coverage, more reliable property predictions, and a stronger regression test suite enabling more accurate simulations in production. Technologies demonstrated include numerical methods, EOS modeling, unit testing, and framework integration.
