PROFILE
Frank Fei
Over a three-month period, contributed core features and stability improvements to the GEOS-DEV/GEOS repository, focusing on advanced simulation capabilities for geomechanics and reactive transport. Developed scalable rock toughness modeling with anisotropic fracture support and refactored parameters for enhanced configurability using C++ and CMake. Delivered phase-field nucleation modeling for hydraulic fracturing, integrating a phase-field solver and damage-coupled constitutive models for porous materials. Implemented a single-phase reactive transport solver with HPCReact integration, enabling thermal fluid dynamics and multiple reaction models. Strengthened CI/CD workflows by refining test execution and YAML-based configuration, improving build reliability and supporting robust scientific computing development practices.

Jan 1, 2026January 2026 (GEOS-DEV/GEOS): Core capability delivered and CI reliability improved. Implemented a single-phase reactive transport solver integrated with HPCReact, enabling thermal fluid dynamics and multiple reaction models. Strengthened CI by disabling unit tests on Ubuntu Debug builds to prevent timeouts and added handling for empty CLI args, reducing false negatives and improving build stability. These work items position GEOS for broader use in reactive transport simulations and faster, more reliable integration cycles.
