Abstract
FaSTAR-Move, an extended version of the fast unstructured-grid flow solver FaSTAR, is developed to analyse flow field around moving/deforming objects such as external store separation, flutter, rotor, and compressor/turbine of aero-engines.

Reasons and benefits of using JAXA Supercomputer System
JSS is necessary to complete numerical simulations of unsteady phenomena and to understand it in short time span.
Achievements of the Year
FaSTAR-Move have been extended to enable rotor-stator steady analysis for rotating cascade and rotorcraft analysis with conplex geometry. It was comfirmed that FaSTAR-Move can reasonably simulate the flow field around them.
