Reasons and benefits of using JAXA Supercomputer System

CFD analysis of several hundred million points is necessary to resolve turbulence generated over complex terrain and to understand aircraft dynamics. Therefore, it is essential to use JSS3, which boasts a large memory capacity and high computational processing power.

Achievements of the Year

Terrain-induced turbulence at several regional airports was analyzed using a solver with a track record in wind engineering. As a result, the location and mechanisms of turbulence were identified.
