Abstract
Utilize the simulation technology of Reserch Unit III to deal with the technical problem solving in current JAXA project, and respond to the request for the project concerning issue. In addition, it realizes “added value (efficiency improvement, high reliability, cost / period reduction, ripple effect, etc.)” unique to numerical simulation technology.

Reasons and benefits of using JAXA Supercomputer System
In order to respond timely to project requirements, it is necessary to simulate complex geometries of actual spacecraft and to analyze a large number of conditions in a short period.
Achievements of the Year
With regard to JAXA projects such as H3, SLIM, MMX, HTV-X, and so on, evaluation of design and risks as well as studies for improvement were carried out by making full use of the simulation technology of Reserch Unit III and JSS3.
