This research aims at reducing the time required to generate computational grid for inviscid as well as viscous flow simulations. The method is based on hexahedra grid method, as the extension of Cartesian grid method. As the result, the method inherits significant advantages of Cartesian grid: it is automatic and fast. Because an efficient viscous flow simulation requires grid with high aspect ratio near solid surface, a hybrid with prismatic grid is necessary. The hexahedra grid extends naturally to this approach, because there is consistency in grid topology (both Cartesian and prismatic grids have the same hexahedral shape). The main idea of the method is as follows: construct Cartesian grid, remove the cells near solid surface, and construct hexahedral cells based on the Cartesian cells' faces toward the surface. Note that both grids are not constructed from the solid surface. This leads to another advantage: the method is not sensitive to defects in solid surface (e.g. crack, overlap), because it actually reconstruct the solid surface grid. However, because of the way the hexahedral cells are constructed (simple projection from Cartesian grid cells' faces toward solid surface), there is a disadvantage: it can not capture sharp concave features. A method to overcome this problem is devised in the present research. This paper provides the summary of the method being developed as well as some current results.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0048469043","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-04-012","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 Space Technology and Aeronautics"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Lahur, Paulus R."}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Lahur, Paulus R.","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":"48469043.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"48469043.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6483/files/48469043.pdf"},"version_id":"7f7597d0-db01-49f1-b0b8-aa741eaac886"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"6面体","subitem_subject_scheme":"Other"},{"subitem_subject":"CFD","subitem_subject_scheme":"Other"},{"subitem_subject":"3次元物体","subitem_subject_scheme":"Other"},{"subitem_subject":"格子生成","subitem_subject_scheme":"Other"},{"subitem_subject":"アルゴリズム","subitem_subject_scheme":"Other"},{"subitem_subject":"計算格子","subitem_subject_scheme":"Other"},{"subitem_subject":"粘性流","subitem_subject_scheme":"Other"},{"subitem_subject":"直交格子","subitem_subject_scheme":"Other"},{"subitem_subject":"航空機設計","subitem_subject_scheme":"Other"},{"subitem_subject":"hexahedron","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CFD","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"three dimensional body","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"grid generation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"algorithm","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computational grid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"viscous flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Cartesian grid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aircraft design","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Flow simulation method based on hexahedra grid","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Flow simulation method based on hexahedra grid","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1073","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6483","relation_version_is_last":true,"title":["Flow simulation method based on hexahedra grid"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:54:54.970804+00:00"}
