Over two months, Shegunov focused on stabilizing and maintaining the Xiangyu-Hu/SPHinXsys simulation framework, addressing runtime issues and improving code clarity. He refined kernel registration logic in C++ to ensure computing kernels were conditionally registered only for relevant particle interactions, reducing overhead and preventing misregistrations. Shegunov also enhanced test reliability by fixing initialization routines and updating type aliases to reflect spatial-temporal representations. Additionally, he improved repository hygiene by removing unused test files, streamlining the test suite for more reliable CI feedback. His work emphasized code cleanup, refactoring, and robust software engineering practices, contributing to the maintainability of the project.
