| Outline of Final Research Achievements |
Simulating how air or water flows around athletes during sports is quite difficult because of the many factors that need to be considered. We have created a cutting-edge tool that can mimic real-life conditions in computer simulations with good accuracy. This tool is a result of two major breakthroughs: one that can precisely represent complex shapes and situations, and another that makes the computer program more efficient when working with moving or changing shapes. With this new tool, we have been able to study real-life sports, like swimming and ski-jumping, in a way that was never possible before. This could lead to new discoveries and improvements in sports science and engineering.
