During January 2026, Minghao Zhou developed a 2D Womersley flow simulation for vessel stenosis within the Xiangyu-Hu/SPHinXsys repository. This feature enables more accurate modeling of hemodynamics in stenotic vessels by simulating complex flow patterns using SPH-based methods. Minghao enhanced data handling for particle dynamics to support the new simulation, ensuring robust data pipelines and facilitating detailed analysis. He also implemented regression tests to verify model reliability and maintain code quality. The work leveraged CMake for build configuration and XML for data management, demonstrating depth in simulation development and data analysis, though no major bug fixes were addressed this month.
