In order to shorten the computational time, a fast CFD code “FaSTAR” has been developed. We combined two acceleration techniques. One is a convergence acceleration technique such as the multigrid method. A coarse-grid generation method using octree data of the Cartesian grid is proposed. This method is simple and it can generate high-quality coarse grids. The other is a programing technique such as data structure improvement and performance tuning. We demonstrate the high-speed performance of the code for aerodynamic computation of a standard aircraft model, NASA-CRM. The computational time is less than one hour using 10 million cells and 100 CPU cores. It is found that the multigrid method is beneficial for large-scale problems.","subitem_description_type":"Other"}]},"item_7_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: 図版あり","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains illustrations","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1520034000","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本航空宇宙学会"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Aeronautical and Space Sciences"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.2322/jjsass.63.96"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.2322/jjsass.63.96","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-6460","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11307372","subitem_source_identifier_type":"NCID"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構航空本部（JAXA）"},{"subitem_text_value":"宇宙航空研究開発機構航空本部（JAXA）"},{"subitem_text_value":"宇宙航空研究開発機構航空本部（JAXA）"},{"subitem_text_value":"株式会社菱友システムズ"},{"subitem_text_value":"大興電子通信株式会社"},{"subitem_text_value":"株式会社計算力学研究センター"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Ryoyu Systems Co., Ltd"},{"subitem_text_language":"en","subitem_text_value":"DAIKO DENSHI TSUSHIN, LTD."},{"subitem_text_language":"en","subitem_text_value":"Research Center of Computational Mechanics, Inc."}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"橋本, 敦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"村上, 桂一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"青山, 剛史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"菱田, 学"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"坂下, 雅秀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ラフール, パウルス"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hashimoto, Atsushi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Murakami, Keiichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoyama, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hishida, Manabu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakashita, Masahide","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Lahur, Paulus","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"CFD","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Compressible Flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Unstructured-Grid","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"高速な非構造格子流体ソルバFaSTARの開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高速な非構造格子流体ソルバFaSTARの開発"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-08-12"},"publish_date":"2015-08-12","publish_status":"0","recid":"22619","relation_version_is_last":true,"title":["高速な非構造格子流体ソルバFaSTARの開発"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:18:06.119605+00:00"}
