During October 2024, Daniel Abele refactored the Normals module in the ISSMteam/ISSM repository to streamline normal vector calculations for Penta, Tetra, and Tria geometries. He consolidated these calculations into shared C++ functions, LineSectionNormal and TriangleFacetNormal, reducing code duplication and clarifying the geometry processing pipeline. Daniel updated the build system to reliably compile the new Normals.cpp and performed comprehensive code style cleanup to enhance readability and maintainability. His work demonstrated skills in code refactoring, geometry calculations, and build system integration, resulting in a more robust and accessible codebase that supports smoother onboarding for future contributors.
