Over four months, Kong contributed to the Xiangyu-Hu/SPHinXsys repository by developing and refining simulation frameworks for rigid-elastic coupling and multi-resolution particle methods. He implemented robust C++ solutions for neighbor interaction management, mesh adaptation, and damping exclusion, improving both simulation accuracy and runtime performance. Kong integrated Google Test for automated validation, expanded test coverage, and streamlined code through targeted refactoring and cleanup. His work included enhancing numerical methods, optimizing build configurations with CMake, and improving debugging instrumentation. These efforts resulted in more reliable, maintainable, and efficient simulation workflows, supporting faster validation cycles and enabling more accurate physical modeling in SPH-based systems.

Nov 1, 20242024-11 Monthly Summary for Xiangyu-Hu/SPHinXsys Overview: Focused on delivering robust multi-resolution capabilities, improving mesh adaptation fidelity, and enhancing debugging support to accelerate validation and reliability of simulations. The work emphasized single-resolution scenarios, refined neighbor interactions, and clearer debugging outputs to support faster iteration and better numerical stability. Key features delivered and technical improvements: - Inner relation splitting and single-resolution neighbor handling: Introduced SplittingInnerRelation and NeighborBuilderSplitInner to manage inner body relations with splitting for single-resolution configurations; refactored for accurate neighbor interactions and updated configurations. Commits: c26c3606facda8b7e6a29459c477b6f2da710f26; b84c1a27efe3bdb8a5a5352a3a73798394129e20. - Multi-resolution cantilever beam simulation refinement: Enhanced damping handling, neighbor calculations, and debug output to support validation across resolutions. Commit: a4a1fd4885d7788396ce0186ae892e0152c60875. - Mesh adaptation level increase and grid precision adjustment: Increased mesh level by one, refined total level calculations for cell linked lists and level sets, and tightened mesh level search epsilon to improve grid spacing comparisons. Commit: fd2ce911e73a89755e9c2df789b60dc26822e26b. - Internal debugging tool: MultilevelCellLinkedList get_level accessor: Added temporary get_level() accessor to aid debugging of the private level_ member. Commit: edb8a25caf2e9415b7f75f832291f67cc538dfcc. Major bugs fixed (scope and impact): - Stabilized inner-relationship interaction logic under single-resolution configurations to prevent misalignment of neighbors and ensure consistent simulations. - Improved traceability and diagnostics through enhanced debug outputs and accessors for internal data structures. Overall impact and business value: - Increased robustness and accuracy in multi-resolution simulations, reducing validation time and enabling more reliable design studies. - Faster iteration through better debugging tools and clearer configuration behavior for single-resolution scenarios. - Clearer change traceability via commits, supporting easier reviews and onboarding for new contributors. Technologies and skills demonstrated: - C++ refactoring and object-oriented design for neighbor interaction and relation management. - Multi-resolution simulation concepts, damping handling, and mesh adaptation strategies. - Debugging instrumentation and development workflow improvements (temporary accessors for internal state).
