PROFILE
Isak Hammer
Isak Hammer contributed to the pmgbergen/porepy repository by developing robust testing infrastructure and enhancing numerical modeling workflows over a three-month period. He implemented a manufactured-solution framework and convergence scaffolding for the Sneddon module, improving validation and reliability of 2D numerical simulations. Using Python and leveraging scientific computing techniques such as the Finite Element and Boundary Element Methods, Isak refactored code for clarity, standardized imports, and improved type safety with mypy. His work included API enhancements, improved documentation, and test automation, resulting in more maintainable code, better cross-environment compatibility, and a stronger foundation for future development and experimentation.

Dec 1, 2024December 2024 — pmgbergen/porepy: Delivered a Sneddon 2D Functional Test Suite to strengthen reliability and coverage of 2D Sneddon modeling. Implemented a placeholder test file and a convergence-study script to validate numerical solutions against Sneddon's analytical solution across orientations and mesh refinements. This work enhances regression testing, reduces risk of regressions in 2D workflows, and supports CI readiness. Technologies demonstrated: Python scripting, test automation, numerical validation against analytical solutions, and robust commit-driven development.

Nov 1, 2024November 2024: Delivered API-level enhancements for numerical constants and protocol configuration in porepy, along with targeted codebase refactoring and test improvements. Public exposure of NumericalConstants in the API and integration into protocol handling were implemented, including ElasticModuli updated to rely on numerics.characteristic_displacement and the addition of a numerical constants management attribute. Concurrently, codebase refactoring standardized import paths for physics modules (SinglePhaseFlow, MomentumBalance, poromechanics) and updated divergence usage in tests to improve consistency and potential performance. These changes reduce maintenance burden, improve numerical configuration reliability, and lay a foundation for more robust experimentation with material parameters.
