Mattia Poinelli enhanced the ISSMteam/ISSM repository by developing spatially variable intrusion distance functionality for grounding line calculations, improving the realism of ice-dynamics simulations. He implemented this feature across Python and JavaScript classes, updating parameter handling and expanding automated nightly test coverage to validate real-world scenarios. Mattia also addressed a bug in the initialization of grounding line distance input, ensuring robust data handling within FreeSurfaceBaseAnalysis and MasstransportAnalysis modules. His work involved C++ and MATLAB, focusing on algorithm design, data validation, and software refactoring, which collectively reduced maintenance risk and improved the maintainability of the codebase during the development cycle.
