Worked on restoring stability to the Flow360 codebase by reverting a problematic merge from main to develop, focusing on ensuring a reliable development environment. Addressed the issue by removing unintended test files, realigning simulation parameters, and rolling back specific model and output configurations to previously validated baselines. Utilized Python and Git to manage the rollback process and maintain deterministic simulation results. Conducted targeted regression checks to confirm that no new issues were introduced, enabling the team to proceed with confidence. This work emphasized careful use of CI/CD practices and highlighted a methodical approach to maintaining software reliability and reproducibility.
