Reasons and benefits of using JAXA Supercomputer System
Because we can use FaSTAR, which has world-class fast performance.
Achievements of the Year
When condensation occurs in the hypersonic nozzle, condensation heat is added to the flow. CFD was conducted to consider the possibility. The code was completed up to adding the condensation heat by using UCR of FaSTAR.
