Worked on the exasim-project/NeoFOAM repository, delivering robust computational fluid dynamics features and infrastructure over nine months. Developed and integrated advanced turbulence models, solver refactors, and OpenFOAM-compatible outputs to enhance simulation fidelity and interoperability. Applied C++ and CMake to implement parallel computing, distributed testing, and performance optimizations, while maintaining code quality through disciplined refactoring and expanded unit testing. Addressed numerical correctness, stability, and maintainability by fixing critical bugs, improving logging, and automating test infrastructure. The work established reliable, scalable simulation workflows and accelerated release cycles, supporting both high-performance computing and streamlined onboarding for future contributors in a complex CFD codebase.

Feb 1, 2026February 2026 monthly summary for exasim-project/NeoFOAM. Delivered two major enhancements focused on accuracy, maintainability, and readiness for validation: - Spalart-Allmaras DDES turbulence model integrated into neoPisoFoam, enabling more accurate simulations of turbulent flows. Commit: f1f2994521647ec46159c25d64d655d6dccab452. - Solver configuration refactor and code readability improvements, including removal of unused variables and formatting consistency across files, resulting in a cleaner, more maintainable codebase. Commits: d7749ef4938824cdc4070053eb5125627e93b6c7; 19d197d49e7060a8551435f41ca30f033d7d87c8. Major bugs fixed: none reported in February 2026. Focus this month was feature delivery and code quality improvements. Overall impact and business value: The turbulence model integration increases the fidelity of simulations with realistic flow physics, supporting more reliable design decisions and validation efforts. The refactor and readability improvements reduce onboarding time for new contributors, lower the risk of regressions, and streamline future feature work. Together, these efforts position NeoFOAM for accelerated iteration and more robust performance. Technologies/skills demonstrated: turbulence modeling (Spalart–Allmaras DDES), OpenFOAM/NeoFOAM solver integration, code refactoring and maintainability practices, configuration management, and disciplined version-control hygiene.
