Oct 1, 2025Month: 2025-10 — Performance-focused documentation refinement in the pmgbergen/porepy repo to improve developer onboarding and user understanding of the simulation showcases. Key feature delivered: Readme Documentation Improvements for Simulation Showcases. The update consolidates and clarifies Readme.md content, including the number of fractures and the description of fluid injection and production wells, with minor grammar corrections to improve accuracy and readability. Business value: Clear, accurate documentation reduces support overhead, accelerates onboarding for new users and contributors, and aligns expectations with the simulation capabilities, thereby enabling faster experimentation and adoption of the porepy showcases.

May 1, 2025May 2025: Focused on expanding test coverage for forward-mode AD in porepy by adding sparray support and parameterized sparse types. Introduced new fixtures to test across sparray, sps.csc_matrix, and sps.csr_matrix, boosting compatibility and robustness of the forward-mode differentiation pipeline. Commit b7ab213259b645045a4fb3549f8417fb3ec9cb69: MAINT: `test_forward_mode` supports `sparray` (#1424). No major bugs fixed in this period. Overall impact: stronger reliability of the AD workflow, broader sparse representation support, and a more maintainable test suite. Technologies/skills: Python, pytest, parameterized testing, sparse matrices/types, forward-mode differentiation.
