Reasons and benefits of using JAXA Supercomputer System
For large scale computations in the future, programs should be tested under the same computational environment.
Achievements of the Year
The linear cascade (T106A) with cooling holes was analyzed using the FaSTAR-Move, and the computational results were compared with the experimental ones.
