To achieve an N-th order spatial accurate scheme in the many-block solver, hexahedral parent cells are sub-divided into structured N to the third power cells. A finite volume method in a similar manner with structured solver is applied to solve the governing equations in the sub-divided cells. High-order spatial accuracy is achieved by interpolating the primitive variables at the cell interfaces of sub-divided cells with a fifth-order polynomial. The developed fifth-order many-block solver is tested for the Taylor-Green vortex problem at Re = 1600. The time evolutions of kinetic energy, kinetic energy dissipation rate, enstrophy field, and vorticity contours obtained by the many-block solver on a fine mesh with (100×5)(exp 3) cells are in excellent agreement with a reference solution obtained using a pseudo-spectral method. The computational speed and cost of many-block solver are evaluated on the JAXA supercomputer system. The many-block solver achieves a computational speed at 2.2 Tflops on 63 nodes (2016 cores) which is approximately 3.3 percent of the system theoretical peak performance. The computational time and memory usage of many-block solver are approximately 1.4 and 3.3 times higher, respectively, than those of a conventional structured multi-block solver.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1730011024","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-17-004","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松山, 新吾"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuyama, Shingo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"AA1730011024.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1730011024.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3258/files/AA1730011024.pdf"},"version_id":"dbb6ac6c-c608-4d8c-a01d-bad896463f0f"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"メニーブロックソルバーによるフレキシブルな空間高次精度 CFD","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"メニーブロックソルバーによるフレキシブルな空間高次精度 CFD"}]},"item_type_id":"5","owner":"1","path":["1532","1876","1891","1978"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-28"},"publish_date":"2017-12-28","publish_status":"0","recid":"3258","relation_version_is_last":true,"title":["メニーブロックソルバーによるフレキシブルな空間高次精度 CFD"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:06:08.751602+00:00"}
