Reasons and benefits of using JAXA Supercomputer System

The calculation domain is the high pressure turbine - strut - low pressure turbine, so the calculation scale is large and the analysis can only be performed using JSS3.

Achievements of the Year

A large-scale analyses of the high pressure turbine-strut-low pressure turbine were also carried out, and it was confirmed that a reasonable solution could be obtained.
