Reasons and benefits of using JAXA Supercomputer System

In general, ice accretes through multi-physical process and its spatio-temporal scales are broad. Thus a use of JSS is nsessary.

Achievements of the Year

a single-shot-based ice-accretion code, whose aerodynamics part is based on well-developed in-house code, FASTAR, was developed.
