September 2025 monthly summary for pmgbergen/porepy focused on delivering a robust foundation for testing infrastructure, refining physics modeling within FluidBuoyancy, and improving code quality and documentation. Key initiatives consolidated test logic across 2N/3N buoyancy models, refined gravity representation in the AD framework, enhanced user documentation, and cleaned the test suite to improve reliability and maintainability. These efforts reduce duplication, clarify physical representations, accelerate CI feedback, and support clearer mass/energy conservation validation, delivering tangible business value through faster development cycles and higher confidence in numerical results.

August 2025: Delivered new modeling capabilities, enhanced configurability, and CI-friendly improvements across GEOS and PorePy with a focus on business value and maintainability. Key work includes introducing a high-level invariant fluid model for compositional flows, expanding discretization configurability and boundary-data flexibility, enabling mixed-dimensional buoyancy with supporting tests, and stabilizing runtime behavior and CI hygiene.

Summary for 2025-06: Implemented API safety improvement for GEOS stencil connector indices by adding a const read-only accessor and refactoring access to enforce const-correctness. This work enhances stability, reduces risk of accidental mutation, and provides a safer, more reliable API for downstream users.

May 2025 (GEOS-DEV/GEOS): Focused on improving code quality and maintainability around fracture mesh handling by introducing a clear separation between surface mesh additions and fracture-specific logic. This groundwork reduces risk for future changes and enhances testability, onboarding, and long-term stability of mesh-related features.

April 2025 monthly summary for GEOS-DEV/GEOS focused on stability and robustness improvements. Implemented targeted fixes to prevent crashes and improve data integrity in core vector handling and VTK utilities, with measurable impact on maintainability and downstream reliability.

Month: 2025-03 — GEOS repository GEOS-DEV/GEOS Focus: key feature delivery and reliability improvements with an emphasis on developer productivity and release quality. Summary: - Delivered XML Validation Script Enhancements that simplify usage, improve reliability, and standardize validation across XML assets. The update removes the need to specify a validation method (all or git) and defaults to validating all XML files in a given directory. It also enhances error handling for missing directories and absent XML files, reducing manual remediation and CI failures. - The change is backed by a single focused commit and aligns with ongoing efforts to streamline validation workflows and improve maintainability of the XML tooling. Impact: - Reduces configuration overhead and operator error by standardizing validation behavior to a single, predictable mode. - Improves CI reliability and early failure detection by ensuring missing directories/XML files generate actionable errors. - Supports faster onboarding for new engineers by simplifying script usage and expectations. Tech/Skills: - Scripting and refactoring for better usability - Robust error handling and input validation - CI-friendly changes that improve build reliability - Traceability through commit metadata (#3588) for auditing and rollbacks

February 2025: Delivered a comprehensive GEOS simulator build guide for Stanford's Sherlock cluster, enabling reproducible builds and streamlined SLURM-driven sequencing. Documented end-to-end steps from sourcing to deployment, and linked to the GEOS-DEV/GEOS repository. This work improves onboarding, reduces setup time, and supports scalable HPC workflows.

November 2024 (2024-11) monthly summary for GEOS-DEV/GEOS. Implemented Build System Cleanup by removing the obsolete Darwin Clang CMake configuration and updating the PVTPackage submodule hash to reference the correct version. This simplifies the build configuration, improves cross-platform reliability, and reduces potential build issues. Associated commit: d7bb7a5967b5ab62c5c18ba043805e50abb0e72a (fix: feature/omarduran/remove darwing clang cmake config file (#3451)).
