Reasons and benefits of using JAXA Supercomputer System

This is an outdoor terrain-dependent wind analysis of tens of millions of grids, and the use of a supercomputer is essential.

Achievements of the Year

Using OpenFOAM, a mesh of regional airport at low-levels was created and wind LES analysis was performed mainly around Wakkanai Airport.
