Contributed to the DLR-AMR/t8code repository by developing and refining features for computational mesh and CAD integration over five months. Focused on modularizing CAD support, improving mesh data structures, and enhancing build reliability through CMake and CI/CD automation. Applied C++ and C to implement node-specific geometric data storage, optimize CAD shape handling with modern language features, and streamline error handling for mesh geometry APIs. Addressed build system issues and improved documentation to support maintainability and onboarding. The work emphasized code readability, memory management, and robust automation, resulting in a more reliable, maintainable, and geometry-aware simulation framework.

Mar 1, 2025March 2025: Node-specific geometric data storage in the computational mesh (cmesh) delivered for DLR-AMR/t8code. Implemented a function to store node-level geometric data (tags, dimensions, and (u,v)-parameters) within the cmesh and introduced new attribute keys to manage this data, enabling richer representation of geometries. Linked changes to commit 57f530b488326d34d526d4ab67350b5f456af00d. This foundation enables geometry-aware simulations, improves mesh fidelity, and supports downstream analytics. Technologies demonstrated include mesh data structures, API design for per-node attributes, and disciplined version control. No major bugs fixed this month.
