Reasons and benefits of using JAXA Supercomputer System

Due to broadband time and spatial scales of ice accretation, huge computational resources and acceleration of computation by JSS are needed.

Achievements of the Year

a preliminary code for complete multi-shot analysis was developed by implementing a mesh deformation method into the single-shot tool.
