The discretization is called discrete (or discretized) model, while the original differential equation is called continuous model. The properties of both models are expected to be of exact coincidence, but there is always some inconsistency between them. In such a situation, we need to know the inconsistency in order to understand what a result of numerical computation means. Otherwise we might misunderstand it to regard a specific behavior of numerical solution coming from the property of discrete model but not from that of continuous one as a part of behavior of the original equation's solution. Here we show some trial to analyze the numerical instability that occurs in numerical calculation of shock waves, where occurs a typical example of inconsistency between the continuous and discrete models.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063742013","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-07-016","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"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"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 総合技術研究本部"}]},"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 Institute of Aerospace Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"相曽, 秀昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aiso, Hideaki","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":"2020-01-16"}],"displaytype":"detail","filename":"63742013.pdf","filesize":[{"value":"530.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"63742013.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5619/files/63742013.pdf"},"version_id":"88150487-f960-436c-a04c-bc448fa06dea"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"数値解析","subitem_subject_scheme":"Other"},{"subitem_subject":"微分方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"離散モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"離散化","subitem_subject_scheme":"Other"},{"subitem_subject":"収束","subitem_subject_scheme":"Other"},{"subitem_subject":"打切誤差","subitem_subject_scheme":"Other"},{"subitem_subject":"線形安定性","subitem_subject_scheme":"Other"},{"subitem_subject":"2次元モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"圧縮性流体","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃波","subitem_subject_scheme":"Other"},{"subitem_subject":"オイラー運動方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"differential equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"discrete model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"discretization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"convergence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"truncation error","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"linear stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"two dimensional model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"compressible fluid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"shock wave","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Euler equation of motion","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"連続モデルと離散モデルの適合性から見た信頼性の議論","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"連続モデルと離散モデルの適合性から見た信頼性の議論"}]},"item_type_id":"5","owner":"1","path":["985","1542","1886","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5619","relation_version_is_last":true,"title":["連続モデルと離散モデルの適合性から見た信頼性の議論"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:10:53.273979+00:00"}
