Abstract
An aerodynamic optimization library “Harmonee,” which uses the unstructured CFD code FaSTAR, is develped and its validity and efficiency are examined. A Multi-Objective Evolutionary Algorithm (MOEA) is employed as an aerodynamic optimization method. This tool is aimed to enable the direct evolutionary computing to perform within a practical computational time by utilizing the high speed performance of FaSTAR. In the present project, basic programs are developed and validated using JSS.

Reasons and benefits of using JAXA Supercomputer System
Aerodynamic optimization using an evolutionary algorithm requires a number of high-fidelity and large-scaled computations (3D RANS analysis) and needs to use the supercomputer.
Achievements of the Year
The surrogate model assisted module of ‘Harmonee’ and ‘WingBoxGen’, structure sizing tool developed by JAXA, were applied to the multi-objective optimization problem for the aero-structural design. We improved Harmonee and comfirmed that reasonable pareto optimal solutions were obtained faster than before.
