In two-dimensional analysis, by using only the 5-point finite difference matrix as the preconditioner, the linear systems can be solved efficiently by the Tridiagonal Factorization CGS algorithm, which can be easily vectorized. The method is also applicable to three-dimensional problems by using the 7-point finite difference matrix as the preconditioner. These techniques are employed to realize a fast 3-D fluid flow simulation system. Numerical experiments were done on the NEC SX-2 supercomputer. Results show that the TFCGS algorithm is 1.3 times faster than the conventional ILUCGS method. By using the 7-point TFCGS method, a very high vector ratio of 99.9% is achieved, and the computation speed of the vector mode is 53 times as fast as that of the scalar mode.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0010004","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL SP-10","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"日本電気株式会社"},{"subitem_text_value":"日本電気株式会社"},{"subitem_text_value":"日本電気株式会社"},{"subitem_text_value":"日本電気技術情報システム開発株式会社"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"C&C Information Technology Research Laboratories, NEC Corporation"},{"subitem_text_language":"en","subitem_text_value":"C&C Information Technology Research Laboratories, NEC Corporation"},{"subitem_text_language":"en","subitem_text_value":"C&C Information Technology Research Laboratories, NEC Corporation"},{"subitem_text_language":"en","subitem_text_value":"NEC Scientific Information System Development Ltd."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"秋葉, 幸範"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"速水, 謙"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"土肥, 俊"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石原, 誠治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Akiba, Yukinori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hayami, Ken","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Doi, Shun","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishihara, Seiji","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":"2020-01-28"}],"displaytype":"detail","filename":"nalsp0010004.pdf","filesize":[{"value":"529.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0010004.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43333/files/nalsp0010004.pdf"},"version_id":"6da7bc03-73b0-429b-958a-5f69490745a9"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"高速連立一次方程式解法を用いた2,3次元流体解析システム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高速連立一次方程式解法を用いた2,3次元流体解析システム"}]},"item_type_id":"3","owner":"1","path":["1893","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"43333","relation_version_is_last":true,"title":["高速連立一次方程式解法を用いた2,3次元流体解析システム"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:17:12.307079+00:00"}
