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
Mesh-deformation techniques in the basic multi-shot method implemented in the last year have been improved and can now be applied to three-dimensional calculations.
