| Outline of Final Research Achievements |
The results of this research contributed to the development of algorithms to enable large-scale fluid simulation. Large-scale fluid computation is widely in demand in industry, for example, for tsunami and landslide damage prediction, computational wind tunnel experiments for aircraft, and special effects scenes in the film industry. However, large-scale fluid computation is known to be computationally expensive, and as a result, the number of trial-and-error attempts for geometry optimization problems is limited. In order to solve this problem, this research has devised various algorithms that achieve variable numerical accuracy in space. As a result, a number of methods that are more practical than conventional methods were developed and its practicality was demonstrated.
